A basic example of the drawing API text object
This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.common.tooltips.js"></script>
<script src="RGraph.drawing.text.js"></script>
<script src="RGraph.line.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="250">
[No canvas support]
</canvas>
This is the code that generates the chart:
<script>
bar = new RGraph.Bar({
id: 'cvs',
data: [4,8,6,3,5,2,6],
options: {
xaxisLabels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
tooltips: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
marginLeft: 35,
marginRight: 35,
textSize: 14,
textFont: 'Segoe UI'
}
}).draw();
new RGraph.Drawing.Text({
id: 'cvs',
x: bar.canvas.width / 2,
y: 22,
text: 'A custom title using the drawing API text object',
options: {
tooltips: ['A custom title using the drawing API text object'],
tooltipsEvent: 'mousemove',
font: 'Segoe UI,Arial,sans-serif',
italic: true,
bold: true,
halign: 'center',
valign: 'bottom',
colors: ['gray'],
size: 16
}
}).draw();
</script>
