How is it posible to use negative numbers?

[Frits1969]

Hello,

I use a negative number. Then I don't get a line. But wen I don't, everything will be ok.
How is it posible to use negative numbers?
This is my code and thanks for help already.
`$(document).ready(function () {
$.jqplot._noToImageButton = true;
$.jqplot.config.enablePlugins = true;

var line1 = [["2018-05-02","15.00"],["2018-05-03","280.00"],["2018-05-05","-60.00"]] ; ?>; 
									 
var plot1 = $.jqplot("chart1", [line1], {
	seriesColors: ["rgba(207, 129, 51, 0.7)"],
	highlighter: {
		show: true,
		sizeAdjust: 1,
		tooltipOffset: 9
	},
	grid: {
		background: 'rgba(57,57,57,0.0)',
		drawBorder: false,
		shadow: false,
		gridLineColor: '#666666',
		gridLineWidth: 1
	},
	legend: {
		show: true,
		placement: 'outside'
	},
	seriesDefaults: {
		rendererOptions: {
			smooth: false,
			animation: {
				show: false
			}
		},
		showMarker: false
	},
	series: [
		{
			fill: false,
			label: 'totaal'
		}
	],
	axesDefaults: {
		rendererOptions: {
			baselineWidth: 1.5,
			baselineColor: '#444444',
			drawBaseline: false
		}
	},
	axes: {
		xaxis: {
			renderer: $.jqplot.DateAxisRenderer,
			tickRenderer: $.jqplot.CanvasAxisTickRenderer,
			tickOptions: {
				formatString: "%b %e",
				angle: -30,
				textColor: '#dddddd'
			},
			min: "<?php echo $datum1; ?>",
			max: "<?php echo $datum2; ?>",
			tickInterval: "1 days",
			drawMajorGridlines: false
		},
		yaxis: {
			renderer: $.jqplot.LogAxisRenderer,
			pad: 0,
			rendererOptions: {
				minorTicks: 1
			},
			tickOptions: {
				formatString: "€ %.2f",
				showMark: false,
				textColor: '#000000'
			}
		}
	}
});

  $('.jqplot-highlighter-tooltip').addClass('ui-corner-all')

});

Hi @Frits1969

The code produces the following output, can you explain in more detail what you are not seeing or expecting to see.

Your code includes <php> elements, have your confirmed the following is not a server side issue (in php)?

Thanks

@dg-hub , thanks for you reaction.

My line is a sum of all the numbers before.
When all the total values are positive, I get a good line.
When one total value is 0, then I don't get this point.
When one total value is negative, I don't get any line.

I use php 5.6.36
I use jqplot.1.0.9.d96a669

Actually, @dg-hub replied. I only added some labels. :-)
Thank you for posting this issue and being active in this project.
