Hi,

You know that we are working on optimizing the performance of charts. I am happy to share that we are done optimizing the overall performance of the charts – QuickLine chart to start with. Both initial render (drawing chart for the first time) & real-time render (updating chart in real-time) are now blazing fast. With these changes, Visifire is one of the fastest Silverlight charts! This blog contains benchmark figures & samples to corroborate our claim.

You’d feel the need of faster charts only when there is high number of datapoints. For less datapoints any charting component would suffice. Time taken by a component to plot datapoints on a chart for the first time (initial render) is a key metric to decide the performance. We did a small exercise to calculate the number of datapoints a charting component could draw in one second. For comparison we are using Visiblox, a fairly quick chart from Scott Logic. We supplied 10,000 through 50,000 datapoints to both charting components. We repeated the exercise to get 10 sample figures. Later, took an average to find out the number of datapoints that could be drawn in a second. Visifire could draw anywhere between 14,500 to 13,200 datapoints in a second. Whereas Visiblox could draw a maximum of 6,800 datapoints & the performance degraded drastically as the datapoints increased. Below are the benchmark figures:

Note: More the datapoints per second, faster the chart.

Embedded below is the application used to calculate the benchmark figures. You can play around with it & decide who is fast!

Note: Lesser the time taken, faster the chart.

Measuring framerate is a good way of finding the real-time rendering performance of a chart. We have just borrowed some samples from Visiblox post. You can play around with the following sample & decide who is fast!

Note: More the frames per second, faster the chart.

The source code of the above samples is available in these archives [sample1, sample2] for you to verify. The samples don’t contain charting libraries & are to be downloaded separately. Feel free to comment on this exercise.

Cheers,
Chirag

We are pleased to announce the release of Visifire v4.5. It’s challenging to ship an eye-candy, interactive and at the same time fast charts. We love challenges, hence this release – to make the fast charts even faster. When there are large number of DataPoints every second counts. The time taken by chart to appear for the first time (initial render) contributes a lot to the user experience. As the title says initial render is now 2 times faster. Below are some benchmark figures:

Column Chart

QuickLine Chart

Faster initial render not only benefits those who want to draw chart out of large number of DataPoints, but also improves user experience in resource constraint devices like a phone (Windows Phone 7).

Note that initial render has not been optimized for Pie & Doughnut charts yet.

We will continue optimizing to achieve higher speed & better user experience. In that pursuit we are now working on improving real-time rendering speed. Stay tuned.

You can download Visifire v4.5 beta here.

Cheers,
Team Visifire
