Hi!

It only displays 10 data, no more. I have 20. I looked everywhere for ways to increase the number of data, but I couldn't find it. I need a little help with this.

There are a number of examples of Horizontal Bar charts showing more than 10 pieces of data in the demos folder of the download archive. There's also an example shown below.

One thing that I'll add is that the marginInner setting (along with the other margins) can influence the amount of space that's available to you (as well as the height of the canvas (or SVG) of course) so try reducing that to zero (as shown) and then increase it slowly to suit.

Also, you can simply increase the height of the canvas (or SVG) tag that the chart is being drawn on.

hbar = new RGraph.HBar({
    id: 'cvs',
    data: [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15],
    options: {
        marginInner: 0,
        marginTop: 5, // Remember to give space for the title if you have one
        marginBottom: 5
    }
}).draw();
