I think data is cause. Too low for viewing?

Hi, sorry i keep asking about this, but i don't understand what happening...
With the values put "by hand" in the array the same thing happens, this part of the code fails (capture in the previous post)

Code: Select all

aData := {228870.00,118823.08,35779.00,33545.00,26101.00,19070.00,18231.50,17521.00,15675.00,13329.20,7970.00,6761.10,6194.40,5656.50,2414.00,1970.00,450.00,0.00}
aLeg := {"1","","","","","6","","","","","","12","","","","","","18"}

	oObj := GraphPlus():New()

	With Object oObj

	  :GraphData := aData
	  :Legends   := aLeg
	  :ShowLegends := .T.
	  :LegendPos := 0										// 0 = Derecha	/	1 = Abajo
	  :Width := 994
	  :Height := 514
	  :Title := cTitle
	  :Picture := "999999999.99"							// Mascara para los valores
	  :ShowLabels := lLabels								// .T. = Muestra los valores
	  :GraphType := GT_PIE
	  :Draw()

	  Chart_Pie.Image_Chart.hBitmap := :Bitmap()			// Imagen con el grafico
	  
	EndWith

Sort or not sort values in "aData", show or not show labels, always fail
With another values (same len 18) no fail, What i do wrong ? Maybe 18 is too long for pie chart ?
What's wrong with those values, maybe 228870.00 to 0.00 it's too much difference ?
Any help is welcome, Thanks in advance !

Claudio

try with some other values with less difference to see what happens....

Thank you very much Serge, It must be an overlay problem, I think 18 data is a lot, I solved it with a bar graph.
Also the line graph works great for me in two programs !
This library is wonderful and very easy to use, huge work from Mr. Rathinagiri !!!

Hi,

Can you give some sample data and or code?

[Rathinagiri]

May be because of 0%?

Hi,

I solve the issue of charts in another way, I use activex and the charts are made with Javascript with the chart.js lib, so we have dynamic charts inside a form that are very useful for clients but also very pretty, I'm just commenting another option.

Regards,
Javier

Hi Sir Rathinagiri
That .txt contains the array values that cause the failure and those that don't.
In the post above is the code part of the function in which I pass the values to the object.
If you need the full function with how I create the arrays from the tables, I can upload it.

[Rathinagiri]

Thanks for reporting!

Confirmed the bug. If the data is so small that its portion comes to 0 degrees when rounded, there is a problem.

Now changed the code in such a way that, if it is 0 degrees, it will not be shown. Hope it is ok.
