Chart Performance

[George Mills]

I ran this simple test on Syncfusion, Infragistics and ComponentOne

I really wanted to use Syncfusion because of some pluses like your DocIO library etc. But the Chart is not performing well at all compared to competitors.

All 3 are dead simple Line Scatter plots.

I tried throwing 10,000 points at each.

Syncfusion rolled over and died on resize, used the most memory, and axis labels collided.

C1 Didn't blink an eye on resize, used 1/3 the memory, and axises were intelligently calculated.

Infragistics was close behind C1 but coding is a very tedious. But you coudl definitely see it drawing slow on resize.

Just sharing my experience in case I'm doing something really dumb and give you guys a chance to perhaps fix it.

Hi George,
Thanks for evaluating Syncfusion products.

We have a 'FastLine' ChartType that just creates one content presenter and does direct rendering. You could customize the Axis labels with different formats to avoid overlapping.

Please have a look at the attached sample and let us know you have any specific questions.

Thanks,
Jay

The FastLine performance is good.

The "custom" axis is a work around, but the chart should be smart enough to do the right thing on it's own. Rotate text can use up a lot of margin too.

As I resize the other charts they add/remove labeled tics, adjust fonts and in some even cases automatically rotate it.

A "smart" axis is a huge part of good chart.

Hi George,
Thanks for the update. We will consider the smart axis as a FeatureRequest and get this implemented for the upcoming release.

For now, you could handle the Chart sizechanged event and adjust the axis's IntervalCount and Grid's TicksPerIntervalCount to get this working. We will work on a sample and will update you.

Best regards,
Jay

Hi ,

Thanks for your interests in Syncfusion products.

We have handled the Chart sizechanged event and adjust the interval to achieve the smart axis effect. Please find the modified sample . Let us know if you have any questions.

Thanks,
Poorani
