JPGraph - Bar Graphs are not showing values
jpgraph, php
Solution
Apparently the issue has to deal with the fact that JPGraph won't let you overwrite its theme by default. I found by setting the theme to null allowed me to make more extensive changes. IMO, that's a pretty dumb setup, but c'est la vie. Here's what my graph definition looks like now:
$graph = new Graph( $p_graph_width, $p_graph_height );
$graph->SetScale('textlin');
$graph->graph_theme = null;
$graph->SetFrame(false);
The 'graph_theme' line is the new addition made that fixed the issue for me. I hope this helps others in the future as it's not explicitly stated in their API.
Problem
I'm using the latest version of JPGraph and I'm trying to alter the graph_api file to show values on Group Bar Plots. Here's a snippet of code to show my alterations (for those looking at the API, this is in the graph_group function): ``` $tot = new BarPlot( array_values( $total ) ); $tot->value->show(); $tot->value->SetFormat('%2d'); $tot->value->SetColor('black','black'); $tot->value->SetFont($t_graph_font,FS_BOLD,9); $tot->SetFillColor('lightblue'); $tot->SetWidth(0.7); $tot->SetLegend( lang_get( 'legend_total' ) ); $graph->Add($tot); $p1 = new BarPlot( array_values( $p_metrics['open'] ) ); $p1->SetFillColor( 'yellow' ); $p1->SetWidth( 1 ); $p1->SetLegend( plugin_lang_get( 'legend_opened' ) ); $p1->value->show(); $p1->value->SetColor('white','white'); $p1->value->SetFormat('%2d'); $p1->value->SetFont($t_graph_font,FS_BOLD,8); $p1->SetFillColor('red'); $p1->SetLegend( lang_get( 'legend_still_open' ) ); $p2 = new BarPlot( array_values( $p_metrics['closed'] ) ); $p2->SetFillColor( 'blue' ); $p2->SetWidth( 1 ); $p2->SetLegend( plugin_lang_get( 'legend_closed' ) ); $p2->value->show(); $p2->value->SetFormat('%2d'); $p2->value->SetColor('black','black'); $p2->SetFillColor('forestgreen'); $p2->SetWidth(0.5); $p2->SetLegend( lang_get( 'legend_closed' ) ); $gbplot = new GroupBarPlot( array( $p1, $p2 ) ); $gbplot->value->show(); $graph->Add( $gbplot ); ``` According to the API, using "value->show()" should display the values. When I add in that last line (for $gbplot), the graph doesn't show. If I comment it out, the graph will display sans values. What am I missing?
