Changing axis min/max on an existing plot using Flot JQuery Library
Solution 1
After you set the value of the yaxis max height, try
yourPlot.setupGrid();
Not sure if it'll be as smooth as you want but I think it does the trick.
Solution 2
You can also dynamically modify MIN/MAX parameters in axis options:
plot.getAxes().xaxis.options.min = 0;
plot.getAxes().xaxis.options.max = 999;
plot.setupGrid();
plot.draw();

I've created a series of plots using the flot library, which are all displayed on a single page. Is there a way to update the X axis min and max options (options.xaxis.min, options.axis.max) values WITHOUT re-plotting the plots ($.plot('placeholder',data,options))?
I found this solution: http://osdir.com/ml/flot-graphs/2012-02/msg00064.html Which suggests that the following line would do it, but it does not work for me - the plots visible min and max are not modified based on this call.
monitorGraph.getOptions().xaxis[0].max = xaxis.max;
Any tips on updating the graphs xaxis max and min values would be greatly appreciated!
EDIT: Solution Below
The following code will take an existing plot, update the range that is visible, and redraw it in a very light and efficient way.
plot.getOptions().xaxis[0].min = time.start; plot.getOptions().xaxis[0].max = time.end; plot.setupGrid(); plot.draw();

jfaghihnassiri almost 11 yearsThis helped a lot! Major improvement over calling .plot each time. Thank you!
-
jfaghihnassiri almost 11 yearsOops, at second glance it seems myPlot.setupGrid(); also does not update the plot visually in any way. Any ideas?
-
matty-d almost 11 yearsHmmm I went on flot's website and just dicked around in the console. Maybe try setupGride then also try draw()?
-
matty-d almost 11 yearsand are you sure that you did "monitorGraph.getOptions().yaxes[0].max = whateverheightyouwant" before you did setupGrid()?
-
jfaghihnassiri almost 11 yearsI tried both in a row and they seem to not effect the plots - although that is what the flot website says they are supposed to do. There may be an issue with how I am storing my plots. Thank you for your help!

matty-d almost 11 yearsYeah make sure the variable you are using in place of "myPlot" is actually a reference to your plot. And if it works out, accept my answer! Cheers
