I want to create a legends for a bar chart, which looks like:
| | | |
/ / / /
where | : data column, / : is a legend for each column
I couldn't get the text legend right, try multiple maxtrix transformation, but none works correctly.
for (int col = 0; col < 4; col++) {
// Draw emotions legends
applet.fill(100);
applet.textFont(font, 20);
// perform matrix transform
applet.rotate(-0.75f);
applet.translate(col * columnW, h);
// draw text
applet.text(legends[col], 0, 0);
// undo matrix
applet.translate(-col * columnW, -h);
applet.rotate(0.75f);
}
Please help :(
