How to increase jqplot from an external button?

Question

I use the jqplot chart to draw a graph, it works great. To scale the chart, I use the cursor, and with this cursor I can scale, but I'm trying to zoom in from a button that is outside the chart. Because we reset the enlarged diagram from an external button like this $('#reset').click(function() {plot1.resetZoom() }); , so you can make an enlargement diagram from an external button. Please advice ...

Thanks in advance...

Answer 1

Sorry, this is not a complete answer, because I do not see the desire that I ever wanted it, but you have two options, as I see it:

• You can define your “scaling factor,” which you would apply to min (x, y), max (x, y), then replot() with the new parameters. The disadvantage of this is that you cannot zoom out with a double click. You can call replot() using the default zoom factor for the custom double-click handler.
• You can find out which handlers are involved when clicking and dragging a chart and simulate this with fixed coordinates - basically a “zoom factor” again

Hi Swan, I think you need to use this function. Enable scaling of the graph. I hope it will be useful for you. All the best

Again, jqPlot is a terrific javascript image library that supports many useful features. In addition to interactive histograms. Here is a plugin that allows you to capture click events for histograms.

 $.jqplot('Graph', data, { barClickable: { onClick: function(i, j, data){ alert("Clicked series: " + i + ", data point: " + j + ", data: " + data); } }});
