    @ngaborabsurd-hu,

    Chart seems to be rendering with 3 dataseries but datapoints passed to the chart seems to be empty. Also, we observed that you are using older version of CanvasJS. Kindly download the latest version of CanvasJS Charts from our download page.

    If the issue still persists, kindly create a JSFiddle with sample data reproducing the issue you are facing and share it with us so that we can look into the code, understand the scenario better and help you resolve it.

    Vishwas R

    @dpanscik,

    In case of chart types like line, column, area, candlestick, etc. X axis is placed horizontally & Y axis vertically. However, they are inverted in case of bar chart.

    Vishwas R

    Jim,

    Setting minimum & maximum properties should work fine in this case. Please find the code-snippet below.

    axisY: {
  minimum: 0,
  maximum: 30000
},
axisY2: {
  minimum: 0,
  maximum: 12000
}

    Vishwas R

    @stockprophet1,

    You can zoom either horizontally, vertically or both by setting zoomType property. You can try setting zoomType: "y" to zoom vertically. Please refer to our documentation for more customization options available.

    Vishwas R

    @stockprophet1,

    Based on the link that you have shared, zoomEnabled property is set at stockchart level instead of chart level. Setting it at chart level (in RSI chart) should work fine in your case. Please find the code-snippet below.

    var rsiDPS = calculateRSI(data);
stockChart.addTo("charts", {height: 100, zoomEnabled: true, axisY: [{minimum: 0, maximum: 100, stripLines:[{value:30}, {value: 70}]}],data: [{type: "line", name: "Relative Strength Index (RSI)", showInLegend: true, yValueFormatString: "00", dataPoints: rsiDPS}], legend: {horizontalAlign: "left"}});

    Vishwas R

    @jtian,

    Glad that you figured it out :)

    Yes, as you have mentioned setting toolTipContent to null will hide information related to that particular dataseries from the tooltip.

    @stockprophet1,

    You can enable zooming in chart by setting zoomEnabled property to true. Please take a look at ‘Behavior of Zoom / Pan’ section in this documentation page for more information along with example.

    Vishwas R

    @rubiconx,

    Pushing datapoint values to different arrays & passing them in multi-series chart options should work fine in this case. Please find the code snippet below.

    
<?php
$dataPoints1 = array();
$dataPoints2 = array();

$con=mysqli_connect("localhost","root","","test"); //mysqli_connect("host","username","password","db"); - Refer https://www.w3schools.com/php/func_mysqli_connect.asp for more info

if (mysqli_connect_errno()) {
	echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql="SELECT xval,yval1, yval2 FROM datapoints";

if ($result=mysqli_query($con,$sql)){	  
	foreach($result as $row){
		array_push($dataPoints1, array("x"=> $row["xval"], "y"=> $row["yval1"]));
		array_push($dataPoints2, array("x"=> $row["xval"], "y"=> $row["yval2"]));}
}

mysqli_close($con);
?>

window.onload = function () { 
	var chart = new CanvasJS.Chart("chartContainer", {
		animationEnabled: true,
		exportEnabled: true,
		theme: "light1", // "light1", "light2", "dark1", "dark2"
        exportEnabled: true,
		title:{
			text: "PHP Column Chart from Database - MySQLi"
		},
		data: [{
			type: "column", //change type to bar, line, area, pie, etc  
			dataPoints: <?php echo json_encode($dataPoints1, JSON_NUMERIC_CHECK); ?>
		}, {
			type: "column", //change type to bar, line, area, pie, etc  
			dataPoints: <?php echo json_encode($dataPoints2, JSON_NUMERIC_CHECK); ?>
		}]
	});
	chart.render(); 
}

    Vishwas R

    @reva,

    Y-value supports numbers as of now. However, if you like to show it as ‘100 INR’ in the tooltip, you can try setting yValueFormatString to “#,### INR”. To do the same thing in axis-labels, you can set valueFormatString property.

    If you are looking for something else, kindly share your requirements so that we can understand it better and guide you accordingly.

    December 20, 2022 at 6:59 pm in reply to: Negative yAxis #41718

    Vishwas R

    Jim Ginn,

    Axis range depends on multiple factors like y-values of dataseries attached, other chart-options like includeZero, interval, minimum, maximum, etc. In your case, multiple dataseries are attached to secondary y-axis that includes range of values from 0.18 to 281. Hence, auto calculated axis minimum includes a negative interval. Setting minimum: 0 should remove negative values in this case.

    December 20, 2022 at 6:59 pm in reply to: remove series without redraw #41717

    Vishwas R

    Chris Trigg,

    Glad that you figured it out :)

    Thanks for bringing this to our notice, we have updated our documentation accordingly.

    When updateChart parameter is passed as true, it updates the chart automatically after removing dataseries. And it doesn’t when it’s passed as false. Please refer to this documentation page for more info along with live example.

    December 20, 2022 at 6:40 pm in reply to: Canvas bar graph #41715

    Vishwas R

    @ankits,

    Rendering bar chart with positive & negative values seems to be working fine. Can you kindly create JSFiddle reproducing the issue you are facing & share it with us, so that we can look into the code / chart-option being used by you, understand the scenario better and help you out?

    From what we have observed, sometimes things get delayed mostly when we are not able to reproduce the issue or not able to understand the exact scenario, or the solution that we provide may not work properly at your end due to variation in the chart-options being used by you and us. Having a JSFiddle with sample data helps us in figuring out the issue and suggesting an appropriate solution accordingly.

    @edwin-k-biju,

    Can you kindly create JSFiddle reproducing the issue you are facing & share it with us so that we can look into it, understand the scenario better and help you out? We are unable to reproduce the issue as values of xAxis, secXAxis are not known.
