Question

do you use a tool? or just manually make them?

Answer 1

Google charts api/server can make one fairly easily

You specify everything in the URL so it’s easy to update:

http://chart.apis.google.com/chart? chs=600x250& // the size of the chart chtt=Burndown& // Title cht=lc& // The chart type - 'lc' means a line chart that only needs Y values chdl=estimated|actual& // The two legends chco=FF0000,00FF00& // The colours in hex of the two lines chxr=0,0,30,2|1,0,40,2& // The data range for the x,y (index,min,max,interval) chds=0,40 // The min and max values for the data. i.e. amount of features chd=t:40,36,32,28,24,20,16,12,8,4,0|40,39,38,37,36,35,30,25,23,21,18,14,12,9,1 // Data 

The URL above plots in intervals of 2 – so work every 2 days. You’ll need a bigger size chart for every day. To do this make the data have 30 values for estimated and actual, and change the ‘chxr’ so the interval is 1, not two.

You can plot only the days done more clearly with the ‘lxy’ chart type (the first image). This needs you to enter the X data values too (so a vector). Use -1 for unknown.
