Thanks Simon, FusionCharts does look really swish and is probably where I should aim to end up. For the moment though I think I'll get things working with J plot before I investigate FusionCharts more fully.
I came across the answer of how to use platimg to save pd output on the jwiki/Addons/platimg page, where it explains how to Capture Graphics from a isigraph control. Instead of: pd 'visible 0' pd 'isi' pd 'save png' I can substitute: pd 'visible 0' pd 'isi' 'plot.png' writeimg~ glqall'' Or without writing a file: plotpng=: 'png' putimg~ glqall'' I notice that the PNG files created by platimg are bigger than their image3 equivalents. I suspect that this is because they include the alpha channel? Is there a way to write a PNG without alpha channel using platimg (or even better only 256 colours?)? If not I suppose I could just write a GIF instead of PNG. --Simon Ampleman wrote: > I suggest you take a look at FusionCharts v3. > http://fusioncharts.com It is using Flash, and you provide > the data with XML files (easy to output in J), it gives > amazing results on the web and it has a very small footprint. > > However, if you still want to use J plot, you can simply > output them in BMP and use a simple BMP2PNG.exe free software > (http://pmt.sourceforge.net/bmp2png/index.html for example), > to get the PNG output.
