Determine Breaking-Point In Graph/Chart
Jan 27, 2010
finding a function/formula for determining the breaking point (Yvalue) in a graph, that doesn't necessarely equals the maximum value of that curve!
So the curve in the sample is a stress strain curve (tensile test) of a fibre and at the end it breaks and the Y value returns to 0. I would like to determine that Y value before it is 0, so the last Y value before it returns to zero.
I thought of a formula like:
display last y value before it drops with 90%...
but I don't have a clue how to write it in maths...

I am looking for a creative way to display a pie chart within a data point marker of a line chart.
My database has 3 value columns, Type1, Type2 and the Total (Type1 + Type2)
these are recorded per day (Date, in Column A)
I have a line chart that displays the total by date, but I want to find a way to display the percentage split of a particular day by type.
I was thinking to load the chart image into the Data point marker, but i don't think that is the best way as the data is updated daily and I would have to do it each day for a few line charts.
The other way I was thinking about was to have a generic Pie chat in the Line chart (Maybe in a corner) and the pie would update depending on way date series was selected or Mouseover'd)
the way that I am approaching it at the movement (Not the best way and by far not the coolest way. Is to have a list of all the dates in a column next to the Line chart and using some VBA, what ever date is selected in the column the pie chart displays the corresponding data. But eh challenge is that when there is alot of dates, I am going to be scrolling up and down.
I am using Excel 2010, but I cant not use the slicer's as the other users do not have 2010, they have 2007.

I would like combine (overlay) a bubble chart with a connected point scatter chart. I understand that, without VBA, this is not possible. However, I understand that, by using VBA, the markers of a scatter chart can be configured as circles with their size proportional to values in a specified column. This pseudo-bubble chart can then easily be combined with a connected point scatter chart.
My question is: does anyone have any VBA code to share that shows how to configure a scatter chart as the type of pseudo-bubble chart described above.

I am supposed to make an xy scatter graph like the one drawn of paper. The average point need to have a "cross" around it. So far I can just plot the points. I have added the average point as secondary series. I just need to put the "+ sign or cross around" it.

I want to insert a text box into a line graph. I want the box locked onto a data point in this graph. The problem I am having is the graph is updated daily with more data so the point moves so I have to drag the box daily. Is there a way to fix this so it works automatically?

Ok, so here's the trick:
I know how to create combo or mixed graphs with line/bars on single axis, and secondary axis. I even know how to do mixed stacked and unstacked columnar charts...
But how do you depict in single view graph
a single bar (1 datapoint) with a single line (upper control limit e.g. target).?
And I don't want to to use shapes to draw the target line.
I want the target line to be automatically plotted by Excel...

I have a spreadsheet created in Excel 2003 (which is what we use at work, unfortunately).
My employees periodically take a test to ensure they have certain items memorized (or are making progress to that end). The spreadsheet rows show all 46 of my employees, and their test scores. The columns are the dates that the tests are administered. I can create a line graph based on the chart data, and interpolate these data with no problems.
The problem is that there are 46 employees! 46 lines on the same graph make for a very cluttered, hard to understand visual. I want to simplify the view by "filtering out" some of the data.
I have an additional column in my spreadsheet for each employee's work area (Area 1, Area 2, etc), and another column with data based on first letter of last name (the values here could be "A-G", "H-M", "N-S" and "T-Z", for example). I figure i could filter my line graph based on these two columns. For example, somehow select just Area 1, and reduce the number of lines on the graph to 16. Or better yet, Choose "Area 2" AND "A-M" and end up with 7 employees (and therefore 7 lines on the graph).
Here's what i have tried:
1) Select the work area column, and use the Filter, which created a drop-down list at the column heading. When i use this drop-down list, i can easily filter the data in the worksheet by Work Area, but this is not reflected in the line graph, which still shows all 46 lines. The problem was that i forgot that i had set the Calculation Options to "Manual". Setting this to "Automatic" (or leaving it on Manual and pressing F9) solved the problem, as the chart now updates when i use the filters. Calculation options are under the "Formula" tab in 2007, or in Tools -> Options -> [either calculation or formula, i forget what it's called] in 2003.
2) Create several separate line graphs in several separate sheets. I wouldn't want to assign someone else the task of maintaining a spreadsheet of such inefficient design.

Showed a line chart using 2 vertical axis where the first was a single line along the graph (ie. 42%) then the second data series was a single data point that was above or below the line which easily showed if the result lied above or below the threshold.

At the moment I've got a chart with 3 series lines on it and each line has 12 points. I need to select the 12th point on each series in the chart and create a label for it. The 3 lines are Budget, Forecast and Actual and often the Forecast line hits the same points as the Budget line in the chart and every time I try to find a way to select the last point on the Forecast line, I end up selecting the budget one because it's the one in the foreground.
I can select the forecast line with the keyboard arrows, but not the last point.
I also try to zoom in to get it but one of my charts has exactly the same forecast line as budget line and I still need the forecast line because the forecast will change in future.
I can delete the budget line then add it back, but this is difficult and one I'd have to repeat many times because I'm always making graphs and labelling the final point in a series is something I'm going to have to do more often.
How do I select the last point on the forecast line if it's directly behind the budget line?

I am looking to create a dynamic bubble chart. To do this I am using offset to create the series formula which without listing all the data names turns out to be something like this (where 297 will adjust to the number of rows with data): =SERIES(Project!$A$5:$A$297, Project!$J$5:$J$297,Project!$P$5:$P$297,2,Project!$Q$5:$Q$297)
My problem is that by creating the chart in this fassion I am unable to get a unique name for each data point. For example, if row A looks like this,
A5: 1
A6: 2
A7: 3
each data point will be named 1 2 3. How do I either create a new series for each row dynamically or get the specific name from column A to associate with the correct data point?

I am trying to graph the following data in an area chart with line charts superimposed on the area chart. I have a lot of data (and a lot going on) so I'm trying to figure out the best way to show this in excel from a functional standpoing (i can't get this to work in excel!!) to also an asthetic standpoint (dont want it to look terrible or illegible). This is what I'm trying to chart:
1) Weather data (temperature) by region:
So one region, would be: Northwest
I would like the "area" (so a shaded region) to be the min/max of the temperature data for each month.
2) I would like to show the temperature for each year as a line graph on the chart - so you can see if a year falls in or out of the shaded region.
3) I would like to show a company's sales increases across the same months per year as separate line charts. I may choose to just show the biggest outlier year in the end... or to show 2006 (the latest data).
What I am trying to convery with the chart is that the company's sales is or is not tied to weather deviations. I have attached an excel file with the data. I haven't been able to use the area chart or get a two axis chart to work or get it to look even remotely professional.

I have an XY chart that I would like to have the user select a single data point in the chart and be able to add a comment in a table corresponding to that point. For example: if the x-values are in A1:A10, y-values are in B1:B10, the user can select a point, say the 4th point, have some code run that will enter a text string into cell C4. I can manage the code to add the text to the appropriate location, but I'm having trouble with 2 things.
First, how can I ensure that the user has selected a single point (as opposed to the entire series or the chart background)?
And second, how can I determine which point is selected? I think I need to determine the point's item number in the SeriesCollection, then offset that number of rows in my data table. But I can't find a way to retrieve that number.

I have created some charts for my work and one of them is a line chart that spreads across one year with values for each month. Well they want the graph to always show one month ahead of where we are out. So there is actuals in for Sep. but then the line graph drops all the way to 0 for Oct. I don't want to have the graph bottom out when there is a zero. Does anyone know how to fix this?

I was tracking down simple ways to generate ASCII character based bar charts and came across this stunningIncellBarChartExample where the author suggested this can be done using VBA code.
I am very new to Excel and EXCEL VBA. Can someone help me sketch how the coding for the above example (include mixed colors) might be done? Is there a special font that need to be used?

I need to plot percentages over time in a line graph in excel. I don't want to have to do a percentage equation in the spreadsheet, I just want excel to take two sets of values and display the percentage in the chart. For example, I need B1 as a percentage of B2 for week 1, C1 as a percentage of C2 for week 2, etc....

how to get the min value scale value off a graph when .MinimumScaleIsAuto = True?
The reason I ask is that I want to make my baseline for the graph that min number so that names from the x axis are not sitting in the middle of the graph. Incognito Auto Merged Post;I feel real bright...just playing around I found my answer...
With .Axes(xlValue)
.MinimumScaleIsAuto = True
.MaximumScaleIsAuto = True
.MinorUnitIsAuto = True
.MajorUnitIsAuto = True
.Crosses = xlCustom
.CrossesAt = .MinimumScale
.ReversePlotOrder = False
.ScaleType = xlLinear
.DisplayUnit = xlNone
End With

Is it possible to create a chart using spherical coordinates (radius, theta, phi) in Excel? I want to create something similar to this. I would even be willing to write add-in code to create the graph from scratch, but I don't know if that's possible. Is it possible to create a new chart type without using the other chart types as a base?

I am trying to figure out how to activate a macro from each item in a drop down list. I also need the macro to recognize which item is chosen and to use that items data (say cells C3:C11) to create its graph. I know how to create an individual macro that will create a graph for the item but not a general macro that can be used to graph all items just discerning the difference in where the data is (which item to graph). Is this possible????if so please include code (amatuer programmer).

I'm trying to graph a bell curve chart using the following data
Hotels per state
Total
AK
4
NH
5
[Code] ......
As you can see I have states and the number of hotels per state what I need not for statistical purposes but more for "pretyness" is to sort this data in a way that what you get is a somewhat of a bell shape curve graph.
