spline
mode) and
there's a couple of demos for it in
the download archive
(hbar-vartical-line.html and
hbar-vertical-line-multiple.html).
Vertical line charts are not supported natively in RGraph however they can
be achieved using the Scatter chart. With
the Scatter chart, unlike the Line chart, you can specify the X-axis
and Y-axis
coordinates and a connecting
line can be shown as in the example.
Below is the code that's necessary to achieve the vertical line chart. The Y-axis
labels are
specific and used to show the labels for the chart whilst an X-axis
scale is enabled to show
the magnitude of values. The maximum values are set manually - so you may want to add code
that determines these based on the data - as a normal Line chart would.
Read the comments in the code sample below to find out more information.
<script src="RGraph.common.core.js"></script> <script src="RGraph.scatter.js"></script>Put this where you want the chart to show up:
<canvas id="cvs" width="400" height="550" style="float: right"> [No canvas support] </canvas>This is the code that generates the chart - it should be placed AFTER the
canvas
