Updating spline chart two lines on top of eachother

由 ￣綄美尐妖づ 提交于 2019-12-13 21:02:50
问题 I am showing two lines in a single graph updating them each second with a value that is saved into a global variable (both have different global variables). An example of the code can be found here: jsFiddle example.

The cause appears to be in the first addPoint call (line 118). If the first boolean is set to true (like

问题 I am trying to add a chart to my website showing how income earned is divided between two parties. It is essentially the 100% stacked graph in excel that would look something like: Is there a good (ideally inexpensive, since the only one I've found that might do it is Highcharts, which looks great but it's not cheap for what we are doing) tool that we could embed into our website? Ideally it would be great if the user could select a certain price and it would show the percentage below for the
