PO2 Axes Reportlab Graph
text
Body
copied!<p>I have managed to create a 2 axes graph in ReportLab, by overlapping a barchart and linepot. Here is the code for anyone interested in something similar:</p> <pre><code>from reportlab.graphics.shapes import Drawing,colors from reportlab.graphics.widgets.markers import makeMarker from reportlab.graphics.charts.barcharts import VerticalBarChart from reportlab.graphics.charts.lineplots import LinePlot drawing = Drawing(400, 200) data = [(13, 5, 20, 22, 37, 45, 19, 4) ] noOfBars=len(data[0]) bc = VerticalBarChart() bc.x = 50 bc.y = 50 bc.height = 125 bc.width = 300 bc.data = data bc.valueAxis.valueMin = 0 bc.valueAxis.valueMax = 50 bc.categoryAxis.categoryNames = ['Jan-99','Feb-99','Mar-99','Apr-99','May-99','Jun-99','Jul-99','Aug-99'] drawing.add(bc) data3=[[(0.5, 4), (1.5, 3), (2.5, 4), (3.5, 6), (4.5, 4), (5.5, 2), (6.5, 5), (7.5, 6)] ] lp = LinePlot() lp.x = bc.x lp.y = bc.y lp.height = bc.height lp.width = bc.width lp.data = data3 lp.joinedLines = 1 lp.lines[0].symbol = makeMarker('Circle') lp.lines[0].strokeColor=colors.blue lp.lineLabelFormat = '%2.0f' lp.xValueAxis.valueMin = 0 lp.xValueAxis.valueMax = noOfBars lp.yValueAxis.valueMin = 0 lp.yValueAxis.valueMax = 8 lp.xValueAxis.visible=False lp.yValueAxis.visible=False #Hide 2nd plot its Yaxis drawing.add(lp) y2Axis = YValueAxis()#Replicate 2nd plot Yaxis in the right y2Axis.setProperties(lp.yValueAxis.getProperties()) y2Axis.setPosition(lp.x+lp.width,lp.y,lp.height) y2Axis.tickRight=5 y2Axis.tickLeft=0 y2Axis.configure(data3) y2Axis.visible=True drawing.add(y2Axis) renderPDF.drawToFile(drawing, '../tmp/barline.pdf') </code></pre> <p>The only problem is that the 2nd has labels pointing inside the graph. I would like them to be <a href="http://tinypic.com/view.php?pic=ejc21w&s=6" rel="nofollow noreferrer">outside</a> the graph!. I found a property to adjust the ticks (y2Axis.tickRight=5 , y2Axis.tickLeft=0) but the yvalue labels position is yet a mystery!</p> <p>Thanks in advance</p>
