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:
|10000||7 secs.||14 secs.|
|5000||3 secs.||7 secs.|
|10000||3 secs.||5.5 secs.|
|5000||2 secs.||3.5 secs.|
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.
