Background horizontal lines on the HBar chart are not adjusting
Posted by Alek at 17:44 on Monday 14th March 2022[link]
Hi Richard,
I have one more issue to resolve though:
I have very long labels on my horizontal bar chart and I am forced to break them down into multiple lines, which forced me to dynamically increase bottom margin of the chart.
I am using background horizontal lines on those charts and when bottom margin is increased background is not squashed as the rest of the chart, leaving buttom lines below the X-axis
Do you have any suggestions?
Regarding the background grid - it's cached in order to increase the performance of animations.
When you redraw the HBar chart you can do this:
RGraph.cache = [];
Which effectively clears the cache. You might also be able to do this using events (though I haven't tested this):
hbar = new RGraph.HBar({
id: 'cvs',
data: [4,8,6,4,5,8,8],
options: {
}
}).on('beforedraw', function (obj)
{
RGraph.cache = [];
}).draw();

RGraph.cache = [] worked! I didn't use it inside of event though
Thanks so much for quick replies
I am very new to RGraph, but really like it's functionality, flexibility and dynamic nature
