Hi Is it possible to have the colours of the graphs the same? For example on my system at the moment PiHome Temperature Graphs Sensor's Battery Graphs Living Room Sensor 30 is Pink on the PiHome Temperature Graphs and Purple on the Sensor's Battery Graphs Bedroom Sensor 21 is Green on the PiHome Temperature Graphs and Light Blue on the Sensor's Battery Graphs Back Bedroom Sensor 20 is Purple on the PiHome Temperature Graphs and Green on the Sensor's Battery Graphs Comp Room Sensor: 28-0316a2791940 is Dark Blue on the PiHome Temperature Graphs Thanks Kevin

@frogstar51, rainbow function is defined is defined in chart_batteryusage.php and chart_load.php the way this function generate colour for both charts isnt going to be in sync.

function rainbow(numOfSteps, step) {
    var r, g, b;
    var h = step / numOfSteps;
    var i = ~~(h * 6);
    var f = h * 6 - i;
    var q = 1 - f;
    switch(i % 6){
        case 0: r = 1; g = f; b = 0; break;
        case 1: r = q; g = 1; b = 0; break;
        case 2: r = 0; g = 1; b = f; break;
        case 3: r = 0; g = q; b = 1; break;
        case 4: r = f; g = 0; b = 1; break;
        case 5: r = 1; g = 0; b = q; break;
    }
    var c = "#" + ("00" + (~ ~(r * 255)).toString(16)).slice(-2) + ("00" + (~ ~(g * 255)).toString(16)).slice(-2) + ("00" + (~ ~(b * 255)).toString(16)).slice(-2);
    return (c);
}
