ExcelChart UDF - Help & Support

[valiryon]

==Originally posted on the download thread (can't edit/remove it that I can see) ==

When creating charts using _XLChart_ChartCreate(), the chart name is not being set (it seems to work for charts created on a chart sheet).

For example, if I pass "A" into the $sXLC_ChartName parameter, and run _XLChart_ChartsGet(), the chart name is listed as "Chart 1". It is also listed as "Chart 1" in the Layout ribbon with the chart selected in excel.

I've added a messagebox to the _XLChart_ChartCreate() to make sure the value is passed in properly, and it is. The $oXLC_Chart.Name value will display as "SheetName Chart 1" where sheet name is the name of the sheet that has the chart.

Is it possible to get more info on what is wrong? Or perhaps have _XLChart_ChartsGet() also pull the chart title?

This UDF is otherwise very handy so far! Your beta release was perfect timing!

To edit/remove a post you have to have at least a post count of 5 - IIRC.

I'm going to answer your question here.

What version of Excel do you use?

We have noticed a strange behaviour with the name property but haven't been able to find the reason.

[GreenCan]

I confirm that this is an issue on my Excel 2007 as well as Excel 2010.

I didn't notice the issue because I didn't focus on the chart names (yet...)... sorry for this.

In debug mode I get effectively following error:

Error 2147352567 (80020009) 'Not enough storage is available to complete this operation'

for this line:

If $sXLC_ChartName <> "" Then $oXLC_Chart.Name = $sXLC_ChartName

When I use the raw code outside the function, for example

$oChart.Name = "Main Chart"

I get the same error.

I will search for a workaround and if possible for a bugfix.

Changing the chart name in interactive mode (Layout, Properties) works, so I guess we should find what is wrong in the code.

I think this remark explains what's going on.

"This property is read-only for chart objects (embedded charts)."

So you can set the name for a chartsheet but not for a chart object.

In the next version of the UDF the parameter will be ignored for embedded charts work for both chartsheets and embedded charts.

You are correct water but there is a solution...

This works:

$oChart1.Parent.Name = "Name of this Chart"

@valiryon, you can use this as a workaround until we come with a new release. that will be pretty soon (a matter of days).

... I am having a coffee break now

Version 0.2.2.0 has been released.

Have fun testing!

For download please see my signature.

[valiryon]

Awesome, thanks for the prompt help with that.

[water]

@Saxo

Can you please post a screenshot of the chart you get and - if possible - a screenshot of the chart as it should look like?

( to the original post).

Edited February 26, 2012 by water

[Saxo]

Water, thank you for your very fast reply. I'm not sure how to post the image, but it is a normal 2D column chart with dates on the x-axis and price on the y-axis. 2 different columns are shown per date. Hope this helps you in your investigation.

[water]

IIRC you will need to have at least 5 posts before you can add attachments to your posts.

I will test your script tomorrow when I'm in the office and post the results.

[water]

Hi Saxo,

some small changes and your chart should work:

In the UDF please change function _XLChart_ChartCreate. Move line

$oXLC_Chart.ChartType = $iXLC_ChartType

to the end of the function before lines

If $bXLC_ScreenUpdate = False Then $oXLC_Excel.ScreenUpdating = $iXLC_ScreenUpdating
Return SetError(0, $iXLC_ErrorHandler, $oXLC_Chart)

EndFunc   ;==>_XLChart_ChartCreate

Then please modify your script like this:

[Saxo]

Thx water - works great! I have continued with the example. My goal is to calculate Pivot Points (see http://en.wikipedia.org/wiki/Pivot_point) and plot them in the Excel chart per date bar. Is it possible to make such plots and if so, how is it done (preferably with with different coloring and labeling of the 5 points per bar)?

Calculating the Pivot Points inside Excel has faced me with the following issues:

• I would like to format the prices so that they are written e.g. 69,450 instead of 69.450 (I assume that .NumberFormat should be used somehow). Currently the calculations are messed up because of this.
• Is there a smarter way for me to write the same formula accros many rows (other than repeating it in the code like I did)?

Below I have pasted the code like it looks now.

Best regards,

Saxo

@water,

Good fix!

@saxo,

Nice example.

I advise you to put the following line in the beginning of the script:

Global $iXLC_Debug = 2 (or = 1)

This will help you finding issues in your scipt, it helped water finding a bug in _XLChart_ChartCreate.

Thanks for your interest

Hi,

I have not been able to figure out how to add a new series to the chart created. After the _XLChart_ChartCreate I have tried with:

;_XLChart_SeriesSet($oExcel.SeriesCollection(6), $xlLine)

;_XLChart_SeriesSet($oExcel[1].SeriesCollection(6), $xlLine)

;$oNewChartSerie = $oChart1.SeriesCollection.NewSeries

;$oNewChartSerie = $oExcel.SeriesCollection(6)

;_XLChart_SeriesSet($oNewChartSerie, $xlLine)

My aim is to plot a line per calculate point (S2, S1, P, R1, R2) per date, so that it on a date e.g. the second would look something like:

_

_

_

_

_

2

I believe that I with 5 points per day for 5 days would need 25 series where each serie would only contain a value for the date it needs to be calculated for (the rest of the dates would have blank value). I don't know if this is the right way or if there is a smarter way. But I'm stuck as long as I don't know how to add a line to the existing chart.

[water]

Use function _XLChart_SeriesAdd to add a data series to a chart. After the function call please check the returncode, @error and @extended.

To get additional COM error information please set

$iXLChart_Debug = 2

at the top of your script (after #include <ExcelChart.au3> of course).

[water]

Hi Saxo,

to add an additional data series add the following code at the end of your script:

; Add a data series
_XLChart_SeriesAdd($oChart1, $XValueRange, "=Sheet1!R2C8:R6C8", "=Sheet1!H1")
If @error Then ConsoleWrite("Line number: " & @ScriptLineNumber & " - Error: " & @error & @CR)
; Set the type of the data series
_XLChart_SeriesSet($oChart1.SeriesCollection(5), $XlLine)

Edited March 2, 2012 by water

[water]

To set colors on the up and down bars and to make the bars smaller (by increasing the gap between the bars) use the following code:

; Format chart
_XLChart_FillSet($oChart1.Chartgroups(1).UpBars, -4)    ; Set the UpBars to green
If @error Then MsgBox(64, "Excel Chart Example Script", "Error " & @error & " returned by function '_XLChart_ChartCreate' on line " & @ScriptLineNumber)
_XLChart_FillSet($oChart1.Chartgroups(1).DownBars, -3)  ; Set the DownBars to red
If @error Then MsgBox(64, "Excel Chart Example Script", "Error " & @error & " returned by function '_XLChart_ChartCreate' on line " & @ScriptLineNumber)
_XLChart_ColumnGroupSet($oChart1.ChartGroups(1), 450)   ; Make the bars smaller (by making the gap between the bars bigger)
If @error Then MsgBox(64, "Excel Chart Example Script", "Error " & @error & " returned by function '_XLChart_ChartCreate' on line " & @ScriptLineNumber)

Thanks water - this managed to move me forward.

• I have now tried to plot in the R2 values per date. For this I can't use $XlLine, because if I used this and only plot one value, then nothing is shown. So as an alternative I have used $xlLineMarkers - but I would prefer that a line (just as wide as the bar) is shown. Is this possible?
• The current $xlLineMarkers solution shows some strange output, because D1, D3 & D4 shows R2 below H (?). R2 should be well above H. Is this an error?
• If point 1) can be solved, then I would like R2 on each date to look the same in terms of color and style (currently Excel picks a new color and marker style per new line that I add). How can this be done?
• Is it possible to call Excel in hidden mode?

The code currently looks like this:

4) To enhance performance and stop flickering you can disable screen updating by adding this at the top of your function

; Disable Screen updating (forced even when debugging is activated)
_XLChart_ScreenUpdateSet($oExcel, 2)

and this at the end of the function

; Enable Screen updating
_XLChart_ScreenUpdateSet($oExcel, 1)

The other "problems" are under investigation.

1) The additonal lines you want to plot should look like the chart you linked to on Wikipedia? A horizontal line with "R1" etc. on both ends?
