Multiple Line Graph

[André Esterhuizen]

Hi  Im using the Line chart and had look at this example

https://developers.google.com/chart/interactive/docs/gallery/linechart#dual-y-charts

what I need to do is to make the x-axis the current year

Y axis 0-300

I want to display current year with dates and marks in blue

Then the previous year date and mark in red

The dates from current and previous year is about the same month but the actual date is diffrent

Attached is a image i created in PAINt what i want to accomplish

Hope it helps

Regards

Andre

var data = new google.visualization.DataTable();
      data.addColumn('date', 'Month');
      data.addColumn('number', "Score -<?php echo $cyear;?>");
      data.addColumn('date', 'Month');
      data.addColumn('number', "Score -<?php echo $pyear;?>");
     // data.addColumn('number', "Average Hours of Daylight");

     // data.addRows([<?php echo $admin->get_score_graph($data['data']['id']);?>]);

[new Date(2014, 0),  -.5,new Date(2015, 0),  5.7],
        [new Date(2014, 1),   .4,new Date(2015, 0),  8.7],
        [new Date(2014, 2),   .5,new Date(2015, 0),   12],
        [new Date(2014, 3),  2.9,new Date(2015, 0), 15.3],
        [new Date(2014, 4),  6.3,new Date(2015, 0), 18.6],
        [new Date(2014, 5),    9,new Date(2015, 0), 20.9],

You didn't make it clear if you looked at the 'Code it yourself on JSFiddle' link in the help file. 

Your rows aren't going in the data table because addRows is commented out. Studying the complete code given in the JSFiddle link should help.
