@fg,

Bar / Column chart accepts 1 y-value & starts rendering bar from the baseline (zero). To pass y-values as a range, you can use range bar / range column chart. Kindly check out our gallery for live examples along with source-code.

@fg,

You can use Range Charts like Range Column Chart, Range Area Chart, etc. in this scenario. Please check out gallery for more examples along with source code.

@tgriffiths,

You can perform AJAX request to fetch stripline values & render chart. Please check the code-snippet below.

/* Index.cshtml.cs */
public JsonResult OnGetStriplineData()
{
	List<StripLine> stripLines = new List<StripLine>();

	DateTime currentTime = DateTime.Now;
	DateTime sTime = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);

	stripLines.Add(new StripLine((long)(currentTime - sTime).TotalMilliseconds, "Label 1"));
	JsonSerializerSettings _jsonSetting = new JsonSerializerSettings() { NullValueHandling = NullValueHandling.Ignore };

	return new JsonResult(JsonConvert.SerializeObject(stripLines, _jsonSetting));
}

/* Index.cshtml */
$.ajax({
	type: "GET",
	url: "/?handler=StriplineData",
	contentType: "application/json",
	dataType: "json",
	success: function (response) {
		chart.options.axisX.stripLines = JSON.parse(response);
		chart.render();
	},
	failure: function (response) {
		console.log(response);
	}
});

Please take a look at this updated sample project for complete code.

@stefan-alfs,

It’s not possible to have different polygon shapes on chart as of now. However, you can use scatter chart to show supported markers / shapes (circle, triangle, square, cross) anywhere with different size within the plot-area as shown in this JSFiddle.

@kfox,

In case of numeric axis chart, labels will be shown at every interval of the axis. Because of this, it’s showing 1 & -1. If there is just one datapoint and your requirement is to show label just for datapoint, you can use category axis (use label instead of x-value). Please take a look at this JSFiddle for an example.

Considering this as duplicate of Single data row barcharts showing 1, -1 rows, hence closing the same.

@mustadirmahmood,

You can align y-axis of both the charts so that the x-axis of both also gets aligned. This can be done by setting axis margin to top chart based on bounds of bottom chart.
chartTop.axisY[0].set("margin", (chartBottom.axisY[0].bounds.x2 - chartBottom.axisY[0].bounds.x1 - chartTop.axisY[0].bounds.x2 + 5));

Please take a look at this updated JSFiddle for an example on the same.

Considering this as duplicate of Make transparent background, hence closing the same.

@ct101,

Please take a look at this Gallery Page for an example on setting color based on datapoint close values in StockChart.

@ct101,

You are using value in labelFormatter instead of label, as you are passing date as label instead of x-value. Please find the updated code-snippet below.

labelFormatter: function(e) {
  return CanvasJS.formatDate(e.label, "HH:MMTT");
}

Please take a look at this updated JSFiddle for complete code.

@swebs,

Y-axis Striplines can be used to show a horizontal line at any desired value. You can set value property to 250 in your case. Please find the code-snippet below.

axisY: {
    stripLines: [{
        value: 250
    }]
}

Sigi,

Datapoints will be plotted at it’s corresponding x and y values. When you increase the width / height of the chart, the corresponding x & y pixel-coordinates of a datapoint gets updated as per the latest size of the chart, but the value of that particular datapoint remains same.

If you are referring to some other issue, kindly brief us more about the same along with an example so that we can understand it better and help you out.

@stefan-alfs,

You can use markers to show circle, square, triangle or cross in line charts. Please refer to documentation for more information along with live examples that you can try out.

If this doesn’t fit your requirements can you kindly share some example or pictorial representation of what you are looking for so that we can understand your requirement better & help you out?
