Re: spline / line graph line styling
which drawing function have you used?
have you tried "Weight"=>2 in the format array like for drawLine?
http://wiki.pchart.net/doc.draw.line.htmlor setSerieWeight("your_serie",2); like for drawLineChart?
http://wiki.pchart.net/doc.chart.drawlinechart.htmlcould be that it works for drawSpline or drawSplineChart too
you could use drawPlotChart with "PlotSize"=>5 to get your dots:
http://wiki.pchart.net/doc.chart.drawplotchart.htmldotted lines are set by TICKS options: setSerieTicks("your_serie",4);
http://wiki.pchart.net/doc.chart.drawsplinechart.htmlyou can combine multiple drawing functions to be rendered into one single chart-image
start with the lines and overlay the dots
