It takes roughly 650ms to draw the bar chart.

You said 2 seconds ... so if it takes 650ms to draw the chart, where are the other 1350ms being spent?

I don't think I'm using gradients in my chart, I don't have any code that explicitly turns them on. Are gradients enabled by default? Is there code I should be using the explicitly turn them off? Yes, gradients are enabled by default - you could turn them off with: tChart1.Panel.Gradient.Visible = ...

Hello Steven, Is there a way to not change the mouse cursor when hovering over invisible parts of this line? This is unfortunately a defect which I have added to our bug tracking software with id=827 . As a workaround, you could try something like the following: private void InitializeChart() { tCha...

Petr, My suggestion is that you do your custom drawing in an event that occurs before the AfterDraw event. There are several options, e.g. private void InitializeChart() { Bar bar = new Bar(tChart1.Chart); bar.FillSampleValues(); Annotation anno = new Annotation(tChart1.Chart); anno.Shape.CustomPosi...

I'm using the barchart series type.. Is there a way to update the series data by only changing the values that change? Instead of clearing the series and repopulating them? If I took this approach would there be a performance gain? No, I don't think so, as the whole chart will still have to be repa...

Adrian, SQL Reporting Services TeeChart.NET includes a palette component for Reporting Services. means, it can be found on the Features page at http://www.steema.com/teechart/net I can confirm that support for SQL reporting services has been dropped from TeeChart.NET. The reason for this was quite s...

Which series type are you using? As a first step, try using a FastLine series type, the best performing series type, to see what difference that makes.

Hello, I am saving all the information of chart in list object and close the form. my requirement is, when i open the form then data present in list should show in chart. this time above line gives error. Would you be so kind as to produce a short, self contained, correct (compilable) example with w...

Can I remove the box around it without resorting to drawing the legend myself? To do that you need: tChart1.Legend.Transparent = true; which you could use in addition to e.g. tChart1.Legend.ColumnWidthAuto = false; tChart1.Legend.ColumnWidths = new int[2] { 10, 300 }; tChart1.Legend.Symbol.Width = ...

Is there any way to Remove the box around the legend? In a perfect world, I would like to position the legend like so http://i57.tinypic.com/69q16g.png Is that possible? Possibly the easiest thing to do here is to draw your own "legend", e.g. private void InitializeChart() { Random rnd = new Random...

Hello, I've recently update my teeChart licence and want to ask if any further research was made about this topic, it keeps being too important to my App to solve it. I'm afraid the only way so far we have been able to speed the import of serialized TCharts with Map series in them is to separate out...

This bug database is public, so please feel free to comment on it. I have made a request for the development team to reapprais...

1) and 2). That is totally right. I have no doubt in that. May I ask, how to perform an automatic zoom that fits all polygon in a given Chart rectangle? Without the use of IsoVertAxes or IsoHorizAxes there is no problem whatsoever. With the use of IsoVertAxes or IsoHorizAxes things become more prob...

On calculating appropriate ratios in maintaining the aspect-ratio, I believe it should also take the Chart bounds into consideration so it may be possible to put all the drawings inside the chart. * Just a vague idea. I do not know whether the above is valid at all. If valid, I treat this as a feat...
