Here is the code:
var data12 = google.visualization.data.join(data1,data2,'full', [[0,0]], [1
], [1]);
var data123 = google.visualization.data.join(data12,data3,'full', [[0,0
]], [1,2], [1]);
var options = {
title:'<?php echo "Accumulated Profit of currencies traded
against ".$coin; ?>',
subtitle: ' in [USD]',
curveType: 'function',
hAxis: { showTextEvery: 10, minTextSpacing: 30},
interpolateNulls: true
};
var chart = new google.charts.Line(document.getElementById('chart_div'
));
chart.draw(data123, google.charts.Line.convertOptions(options));
Each line separately appears fine, but the 3 lines together gives a mess
Here is a print screen:

I read that I have to add
interpolateNulls: true
I tries every option suggested in various forums. No solution.
What can I do to solve the display problem ?
