Unfortunately, its actually a bit of a mess. In different parts of the code, different pens and brushes are being used to draw the area and draw the legend for the area. I am thoroughly confused because the brushes and pens get set over and over again :D However, I think that if I create my own Area...

Hello, As far as I can tell, it seems that someone has forgotten to override the TChartSeries.legendItemColor method for an Area Series. The default behaviour in TChartSeries is to use the seriesColor, but for areaSeries, the seriesColor is not necessarily used. So I think that will work for this bu...

Hi Narcis, Is there any explanation of IStartPos, IEndPos etc. I cannot find it in the help. If there is no help, it would be great if you could you post sample code for the following two functions function getChartRectForBoundsRect(const bRect:TRect):TRect; begin // assuming the tchart boundsRect=b...

is there a way to calculate this?
Is there any function I can call to say: Give me the Chart BoundsRect I need so that the axis lengths will be a certain value. That way I would be able to set the bounds so that my x and y axis will be a specified size. Alternatively, is there a function that returns: Given a specific bounds rect, t...

i have figured out a way to do it partially. If the plot is 100x100 I can do the following: chart1.view3doptions.fontzoom:=200; teecreatemetafile(true,rect(0,0,200,200)) This creates the correct size metafile, with high res for the dot and the fonts come out to be the relatively correct size. The on...

legend filled when it is not supposed to
Hello, I have created an area series that has a no fill, and only the hatch marks from the fill are visible. This worked out just great. Problem is that in the legend, a background color is coming up. So even though the series is red hatched lines on a clear background, in the legend it is coming up...

PixelsPerInch not respected
Hello. How come if I set the chart1.title.font.pixelsPerInch:=500 there is no difference in the font size on the chart as compared to leaving the pixelsPerInch alone. However, if in the formPaint for a form I do canvas.font.pixelsperinch:=500; canvas.font.size:=8; canvas.font.color:=clblack; canvas....

I think I realize what the problem is..... Lets stay my chart is 100 x 100 pixels I realize that if I do chart.printerResolution:=-(100; chart1.drawPartialCanvas(metafileCanvas, rect(0,0,200,200)) its the same as TeeCreateMetafile(true,rect(0,0,200,200)); What I basically need is to have a printerRe...

I have investigated the issue a bit further, and am still a bit confused. I created a TChart that is 100x100. I did a printPartialCanvas with the output rect as (0,0,100,100). Everything worked great, except the background did not print. Is there any way to get the background to print when doing pri...

getting proper resolution graphics
Hello, I have a bit of a tricky problem ( I think). Lets say I have a plot where the x- and y-axes are 100 pixels long. I am also graphing data that possibly goes from 0..99. That means, that each data point should be one pixel, since there is 100 pixels, and 100 possible data values. Everything is ...

Hi Narcis, If you can point our where the root of the problem lies, we will be glad to investigate it. I assume that some canvas brush properties are not being set up properly to work with metafiles. We have already modified the tchart source quite extensively, and will be glad to fix the problem an...

transparent series to metafiles
Hello,
I have charts with transparent series . Whenever I try to get a metafile using teeCreateMetafile, the series are not transparent in the metafile. Is there something I am missing?
