Trying to create a chart as show below
Tried to get most of it working fiddle is in
https://jsfiddle.net/BlackLabel/j1pz28y3/
But only axis is the issue. Unable to get multiple axis for different chart and also axis on the left rather than right please help me by pointing to some demo
You need to set yAxis.opposite to false. Your image shows only two axis (first one for the line and flag series, the second one for the column), so here is the example config basing on the image:
yAxis: [{
opposite: false,
height: '60%'
}, {
opposite: false,
top: '65%',
height: '40%',
offset: 0
}],

I'm working with line-polar eCharts on Angular, and I ran into a problem with areaStyle. I want it to fill the whole area from the line to the outer most circle with the yellow color, but eCharts left out a little bit of empty space. I tried creating a shadowBlur and offsetX, Y it to the blank area, but the color is not the same. Is there a property of areaStyle I'm missing, or is there a library to fix this?
series = [{
coordinateSystem: 'polar',
name: this.legends[1],
type: 'line',
color: '#D9B100',
data: this.datasetCylinder.data,
smooth: true,
showSymbol: false,
lineStyle: {
show: true,
width: 3,
shadowBlur: 10,
shadowColor: 'gold'
},
areaStyle: {
color: 'gold',
origin: 'end',
opacity: 0.1
}
}]
A simple solution would be to add more points in between, but then chart yellow line might not have the correct form. Any suggestion is appreciated.
There is no easy solution but you can try to find it:
Draw the area outside the circle boundaries and then cut the excess with VisualMap.
Cut area in already filled circle by VisualMap with pieces.
Use custom series and draw all with polygons.
I am using scatter chart from eCharts scatter. No option in official documentation about any option for setting the start of axises, I need xAxis starts not from 0, but setting some buffer like in picture
.
So bubble should start not from 0 but having some extra buffer, so the bubble should not overlap the xAxis. I tried boundaryGap for both xAxis and yAxis, but still axises start from 0. Any possible workaround for that?
try to use xAxis: { onZero: false }.
On echarts 5.4 it is
https://echarts.apache.org/en/option.html#yAxis.min
for x xAxis: {min: 'dataMin'} or y yAxis: {min: 'dataMin'}
I'm using echarts
this is my chart
this picture shows I lost some of my legends , so,how do I make bigger space for legends, is it possible to set more space for legends? or if it is possible to make my chart smaller how can I do?
I put
var option = {
grid: {
y: 30,
y2: 90,
},
y mean space before chart, y2 - after chart
I have some info which is in this format (speed, frequency, date). What happens is that I need to plot this chart with speed x frequency, but I want to allow the users to use the navigation filtering by the date, which is not appearing on the chart.
Also, I have some info which is not built dynamically, which is the limits of speed x frequency. This info will be fixed as reference points on the plot. So, when I filter the plot info (not the limits), it must always display these limit plots.
You can have an idea by this chart, the area plots show the limits for the points (speed, frequency). Then, I would add points of speed x frequency (x date), and filter then by date.
Can you guys give me some advice on this?
here is a JSFIDDLE
JSFIDDLE
data: [
[0, 20, here is a date], [10, 20,here is a date],
[50, 39.9994, here is a date], [100,49.7494, here is a date]
],
Guys, notice that every element of the array in the series has 3 elements [a, b, c], suppose the third one (c) is a DATE and not a random number as it is right now. I want to be able to use the commented the navigator code to filter this series by this C element, which doesn't in fact appear on the chart you see, it is a hidden element, just to filter the data.
There will be a little tricky, if you want to have a navigator in the same chart. Navigator works only with datetime data and it must be connected with the axis from the main chart.
So, you have data in that format:
var points = [
[5, 9, Date.UTC(2016, 1, 0)],
[65, 6, Date.UTC(2016, 1, 1)],
...
You need two x axes - one which represents the data and the other which is connected to the navigator. The second axis must be visible to work with the navigator and must be connected with the datetime data.
So now, except two x axes, you need two series - one with the actual data, and the other consists of [date, y] values from the first series. The additional data will be visible in the navigator - note, that in the navigator you cannot use scatter series - so it will be converted to line series - to happen it without errors, your data should be sorted by date.
series: [{
id: 'main-series',
data: points.map(function(point) {
return [point[0], point[1], point[2], point[1]]
}),
showInNavigator: false,
xAxis: 1,
keys: ['x', 'y', 'date', 'holdY'] //holdY is for easier hiding points
}, {
xAxis: 0,
data: points.map(function(point) {
return [point[2], point[1]];
}),
showInNavigator: true,
enableMouseTracking: false,
color: 'transparent',
showInLegend: false
}],
xAxis: [{
minRange: 1000 * 3600 * 24,
type: 'datetime',
tickLength: 0,
tickLength: 0,
labels: {
enabled: false
},
}, {
type: 'linear'
}],
The last thing you need a callback which will hide/show points after the extremes in the navigator are set. Hiding/showing depends on the third point's property which is date. There is no directly API to hide/show specific points (except pie), but it can be achieved by setting point's value to null (that is why I preserved the real y in holdY).
events: {
afterSetExtremes: function(e) {
var points = this.chart.get('main-series').points;
points.forEach(function(point) {
point.update({
y: e.min <= point.date && point.date <= e.max ? point.holdY : null
}, false, false);
});
this.chart.redraw();
}
}

I would consider using a navigator as a separate chart, then you wouldn't need the second x axis and series in the main chart and you wouldn't need to make them look invisible.

If I have a data like this:
data: [0,0,0,0,0,0,0,0,0,0,0,0,0]
this serie starts on the middle but I want what starts really close than the bottom line and not in the middle.Please take a look in this jsfidle http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/xaxis/tickwidth/ but change data by my example data (data: [0,0,0,0,0,0,0,0,0,0,0,0,0]), I test with min but in this scenario with all values in 0 did not work.
Thanks
I solve with min: 0,minRange: 1 in xAxis
I would do this simply by setting the yAxis min and max.
Example:
http://jsfiddle.net/jlbriggs/bKr74/1/
You can move xAxis down using offset property (offset: Number; The distance in pixels from the plot area to the axis line.):
xAxis: {
tickWidth: 10,
offset: -155
},
See example at jsfiddle
