Python- Reportlabs - save 2 different graphs in 2 different pages?

Question

I've the following code where I'm drawing a vertical bar graph and a line graph as well inside a PDF. How do I save these 2 graphs in 2 different pages of the PDF. I saw that it can be done using - ``` c = canvas.Canvas("hello.pdf") hello(c) c.showPage() c.save() ``` But, instead of using Canvas, I'm using Drawing object in which `showPage()` method does not exist. How do I save the 2 graphs in 2 different pages of the PDF? Right the second graph(line chart) overlaps the first graph (vertical bar chart), thereby hindering the bar chart. Here is my code. ``` from reportlab.graphics.shapes import Drawing from reportlab.graphics.charts.barcharts import VerticalBarChart drawing = Drawing(400, 200) data = [ (13, 5, 20, 22, 37, 45, 19, 4), (14, 6, 21, 23, 38, 46, 20, 5) ] bc = VerticalBarChart() bc.x = 50 bc.y = 50 bc.height = 125 bc.width = 300 bc.data = data #bc.strokeColor = colors.black bc.valueAxis.valueMin = 0 bc.valueAxis.valueMax = 50 bc.valueAxis.valueStep = 10 bc.categoryAxis.labe…

Accepted Answer

Make a canvas and render your drawings on it:

```
from reportlab.pdfgen import canvas
from reportlab.graphics import renderPDF

c = canvas.Canvas('hi.pdf')

# your drawing
# drawing = Drawing(400, 200)

x, y = 0, 0 # coordinates (from left bottom)
renderPDF.draw(drawing, c, x, y, showBoundary=False)

c.showPage() # to end a page and start a new one

# extra pages content

c.save() # to save :D the whole document
```

Hope it helps :)
