What's happening with RGraph at the moment?

Written by Richard Heyes, RGraph author, on 24th December 2019

It's Happy Christmas day (more or less)! So I think now would be a good time to let you know what's happening with RGraph.

For the last three weeks, I've been gradually converting the Bar, Gantt, Horizontal Bar, Line, Scatter and Waterfall to all use a single function to draw the x-axis and another function to draw the y-axis.

This means fewer bugs (hopefully) and simpler code that draws the axes (though the functions are rather large). And because the code is centralised in the RGraph.common.core.js library the various libraries can have their own axes drawing code removed and thus leading to a smaller set of libraries.

So have a Happy Christmas, a good new Year and look forward to the next version of RGraph. Let's hope that 2020 will be the year of RGraph!
