Re: How to optimize line series performance

Hello! with reference to the TeeChart Examples demo which you can download from GitHub here , there are two strategies you can try, one specific to the FastLine series and the other available for all TeeChart series types: TeeChartNetExamples_2019-03-18_08-02-52.png and TeeChartNetExamples_2019-03-1...

Re: How can I tell different series to use the same X (Bottom) Axis ?

Hello! The extra line in the code snippet below will force the xaxis labels to render the values of the points and not their labels. By default, the LabelStyle property is set to talAuto which will render the xaxis labels as the string labels of the points. procedure TForm1.Button1Click(Sender: TObj...

Re: Ternary Graph Legend and Points

Hello Errol I would be very grateful if you could create a simple test program that starts with a standard chart, and which displays the results as a ternary graph when the data is specified as a Ternary Series. Of course - I hope this example will be sufficient, If not, do please let me know and I'...

Re: Drawing X and Y axes on chart

Hi Rob, maybe you have in mind something like this: TeeChartPro_2019-02-27_10-46-07.png This can be achieved with code similar to this: private void InitializeChart() { var forvel = new FastLine(tChart1.Chart); var lines = File.ReadAllLines(@"D:\tmp\FastLine Data.csv").Skip(1) .Select(x => x.Split('...

Re: Fastline.Add - load with individual points or pass array

Hello Rob, that'll teach me to read things more carefully! Thanks for your patience in sending me what I had mistakenly expected. The answer is the ordering of the XValues - by default they are ordered, so when you add your values in one-by-one they are ordered. Adding in the values directly to the ...

Re: Circular Gauge Alignment

Hello! Is it possible to left align the chart? Yes, yes it is. You will be able to use the GetAxesChartRect event to define the rectangle in which you want to draw the CircularGauge series e.g.: public Form1() { InitializeComponent(); tChart1.Series.Add(typeof(CircularGauge)).FillSampleValues(); tCh...

Re: Fastline.Add - load with individual points or pass array

Hello Rob, We have been using TeeChart.NET for more than a decade and love it. That's fantastic, we really are so pleased to hear that, thank you! This is working so my question is should we continue with this method and is there some explanation as to why the first method results in FastLine that t...

Re: Setting axis maximum doesn't work in BeforeDrawAxes event (only in BeforeDraw event)

Hello! BeforeDrawAxes event is supposed to be for all axis manipulations, isn't it? not exactly - it's primary function is for drawing custom elements onto the chart at different stages of the chart's drawing routines, as can be seen in the demo here: TeeChartNetExamples_2019-01-30_13-49-28.png give...

Re: UWP logarithmic axis

Hello!

Yes, when Chart.Aspect.GestureOptions != Aspect.Gestures.None the chart axes are 'streched' - if you set:

Code: Select all

Chart.Aspect.GestureOptions = Aspect.Gestures.None;
then I think the images should look the same.
