Thank you! That was so helpful.

First a little background. I didn't find the TChartPreviewer component suitable for my program. It has a number of unnecessary controls for my purposes. Also, I don't like that it is a modal form -- I would have preferred a panel embedded in my own form. Therefore, I am trying to make use of the TTe...

Thank you for clarifying. Regarding the panel margins, how would I access them from code? I don't see Panel as a chart property.

I retract this issue. I discovered that the margins do have an effect if a border has been applied around the Title.

With the default settings, a TChart has a nice gap between the Title and the top of the graph. This is given by the Title Vertical Margin setting. If one selects Chart1.Title.CustomPosition := True (e.g. by double clicking on the chart in the IDE to open the editor and going to Titles>Title>Position...

To reproduce this problem:

1. Drop a TChart on a form.
2. Double click the chart to open the Editor.
3. Select Titles > Title > Margins
4. Drag the Margin trackbars -- nothing happens.

I am using latest TeeChart Pro, Delphi Berlin and Windows 10.

My questions relate to the component TChartPreviewer, not to TTreePreviewPanel. (However, I did try TTreePreviewPanel and it does not "include option buttons" as you state. The reference doc. states that it includes option buttons but I did not find that it did.) I will try to put my two problems re...

I am using the TChartPreviewer component to preview and print a chart. ChartPreviewer.Execute launches a dialog that allows the Panel to be customized extensively with color, a gradient fill, shadow, emboss etc. But the Panel appears to be the area outside the paper, so does not print. I am struggli...

Thanks again. It is working really well for me! One further question please - do you know of an easy way to calculate the area of a SeriesRegion? I have been exploring doing it by establishing a list of points that approximates the region and then applying Green's Theorem in the plane to calculate t...

Thank you. Is it possible to limit the filling to certain discrete ranges of X? I.e. can the SeriesRegion be turned on and off at various X-values?

I have a line series. I would like to fill a region between X1 and X2, above Y1 and below the series. I would also like to fill another region between X3 and X4, above the series and below Y2. (Actually, there are many such regions, but for the sake of the example, suppose there are only two.) Is it...

I'm drawing rectangles on a chart in the OnBeforeDrawSeries event. To draw a rectangle with a solid fill, I define a brush with (for example) Chart1.Canvas.Brush.Color:=clRed; and then draw a rectangle in the OnBeforeDrawSeries event with (for example) Chart1.Canvas.Rectangle(X0,Y0,X1,Y1). If I want...

Steema’s product page for VCL/FMX (https://www.steema.com/product/vcl) states for TeeChart Pro: “You can easily export charts as images (Flash/Flex, XAML, JPEG, GIF, PNG, BMP, EPS, PDF, PCX, WMF)…” However, (at least) three of these export formats do not work correctly. I have not tested Flash/Flex,...

Hi Yeray,

Your suggestion worked!

I had a slight problem at first because Options does not exist on the right-click menu in a Multi-Device (FMX) app. However, after creating a VCL application and following your suggestion, the problem was resolved for both VCL and FMX.

Thanks.

I have uninstalled and reinstalled TeeChart several times but can't get rid of this error. I am using TeeChart Pro VCL FMX Source Code 2016.17 and Delphi 10.1 Berlin. When TeeChart is installed, selecting Tools|Options in the IDE gives the error "'some text in foreign script' is not an integer value...
