Hello, I have a wirking code for a line graph.
Now I want to show 3 lines on the same graph. I created the data Is this the right way for the join of 3 2-dimentional arrays? var data_123 = google.visualization.data.join(data1, data2, data3,'full', [[ 0,0]], [1], [1]); This doesn't work either: var data_123 = google.visualization.data.join(data1, data2, data3,'full', [[ 0,0]], [1], [1], [1]); I looked at the documentation in https://developers.google.com/chart/interactive/docs/reference#google_visualization_data_join I can't understand from this explanation how to join more than 2 arrays. Can anyone explain it to me please is this the right way for chart draw? chart.draw(data_123, google.charts.Line.convertOptions(options), { interpolateNulls:true}); I'm asking because these are [date, value] arrays and I added { interpolateNulls:true} since the dates are not overlapping (I hope this is the correct verb) Thanks -- You received this message because you are subscribed to the Google Groups "Google Chart API" group.
