  • in reply to: How can I plot values from .txt file ? #14967

    Hi,

    this is working to avoid the error. Some remarks for others.

    1) using cache: false, within ajax call else the browser cache exploid with setintervall function
    2) using Timeout function instead setintervall, setintervall will stack tasks if the focus is not on the window
    3) i get problems with refreshing and showing “live” cause my file have 200.000 + lines in it and reread costs me around 1+ seconds some times.

    correct me if im wrong

    best regards

    Hi again,

    the shifting with limited points are working fine thank you ! (i modified source to 3 rows only)

    but if i set an interval now ive got an error every interval

    it say:
    cannot read prperty ‘split’ of undefined
    at processData line 75 (var allLinesArray = allText.split(“\n”);)

    i cannopt find my mistake at the moment -.-

    in reply to: How can I plot values from .txt file ? #14931

    Sure i can :)
    I have some issues im facing rigth now.

    1) the file is text format (csv possible) and really big like 150000 lines

    2) it have 7 rows in a line (123 456 789 999 999 999 999)

    first i tried to build a update function, what happens is i have to run every time ajax read ( i guess so)
    it is really slow and fill up the browser cache pretty fast cause it reread the the copmplete file everytime and store it.

    what i want is to show a live update with the last 1000 lines and shifting the graph.
    I know text format seems not to be the best source

    in reply to: Graph a CSV file with number of points #12579

    Hi,

    I do have a question about graph csv file

    This is how my File look like:

    0 246.438 243.078 114.506 246.438 243.078 114.506
    1 246.438 243.078 114.506 246.438 243.078 114.506
    2 246.438 243.078 114.506 246.438 243.078 114.506
    3 246.438 243.078 114.506 246.438 243.078 114.506
    # any comment
    4 246.438 243.078 114.506 246.438 243.078 114.506
    5 246.438 243.078 114.506 246.438 243.078 114.506
    6 246.438 243.078 114.506 246.438 243.078 114.506
    7 246.438 243.078 114.506 246.438 243.078 114.506

    first: is it possible to use “space” as split value?
    second: how can I ignore lines which begins with # (comment) by parsing

    my code:

    `function processData( allText ) {
    var allLinesArray = allText.split(“\n”);
    if( allLinesArray.length > 0 ){

    var data = [];

    var dataPoints1 = [];
    var dataPoints2 = [];
    var dataPoints3 = [];

    var dataSeries1 = { type: “line” };
    var dataSeries2 = { type: “line” };
    var dataSeries3 = { type: “line” };

    for (var i = 0; i <= allLinesArray.length – 1; i++) {
    var rowData = allLinesArray[i].split(” “);
    if (rowData && rowData.length > 1) {
    if (i != 0) {
    dataPoints1.push({ label:rowData[0], y:parseInt(rowData[1]) });
    dataPoints2.push({ label:rowData[0], y:parseInt(rowData[2]) });
    dataPoints3.push({ label:rowData[0], y:parseInt(rowData[3]) });

    }
    }
    }

    dataSeries1.dataPoints = dataPoints1;
    dataSeries2.dataPoints = dataPoints2;
    dataSeries3.dataPoints = dataPoints3;

    data.push(dataSeries1);
    data.push(dataSeries2);
    data.push(dataSeries3);

    var chart = new CanvasJS.Chart(“chartContainercool”,{
    backgroundColor: “#e5ecf0”,
    animationEnabled: true,
    zoomEnabled:true,
    zoomType: “x”,
    title: {
    text: “cool Data”
    },
    axisX:{
    labelAngle: 0,
    labelWrap:true,
    labelAutoFit: false,
    labelFontSize: 15,
    labelMaxWidth: 200,
    labelAngle: -30,
    labelFontColor: “black”
    },

    data: [
    {
    indexLabelPlacement: “outside”,
    name: “X-Axis”,
    indexLabelFontWeight: “bold”,
    indexLabelFontColor: “black”,
    legendText: “X-Axis”,
    showInLegend: true,
    color: “orange”,
    type: “line”,
    dataPoints: dataPoints1
    },
    {
    indexLabelPlacement: “outside”,
    name: “Y-Axis”,
    indexLabelFontWeight: “bold”,
    indexLabelFontColor: “black”,
    legendText: “Y-Axis”,
    showInLegend: true,
    color: “green”,
    type: “line”,
    dataPoints: dataPoints2
    },
    {
    indexLabelPlacement: “outside”,
    name: “Z-Axis”,
    indexLabelFontWeight: “bold”,
    indexLabelFontColor: “black”,
    legendText: “Z-Axis”,
    showInLegend: true,
    color: “blue”,
    type: “line”,
    dataPoints: dataPoints3
    },

    ]
    });

    chart.render();
    }
    }
    });
