I'm trying to display a line chart based on this data set:
[
{ x: new Date(2018, 1, 1), y: 0 },
{ x: new Date(2018, 2, 1), y: 50 },
{ x: new Date(2018, 3, 1), y: 150 },
{ x: new Date(2018, 4, 1), y: 200 },
{ x: new Date(2018, 5, 1), y: 340 },
{ x: new Date(2018, 6, 1), y: 490 },
{ x: new Date(2018, 7, 1), y: 590 },
{ x: new Date(2018, 8, 1), y: 700 },
{ x: new Date(2018, 9, 1), y: 1230 },
{ x: new Date(2018, 10, 1), y: 900 },
]
My problem:
The x axis labels is duplicated 4 times, so every tick is showed 4 times: feb, feb, feb, feb, mar, mar, mar, mar ...
UPDATE:
Removing the formatting of the date reveals that ´react-vis` renders a tick for each week (feb 4, feb 11, feb 18, feb 25, mar 4, mar 11 ...) But the data has a monthly interval.
How can I make the x axis follow the data?
This is my code:
<FlexibleWidthXYPlot height={300} xType="time">
<XAxis
// tslint:disable-next-line jsx-no-lambda
tickFormat={(d: Date) => formatDate(d, { rawFormat: 'MMM' })}
tickLabelAngle={-45}
// xDomain={[new Date(data[0].x), new Date(data[data.length - 1].x)]}
// xRange={[0, 9]}
// tickValues={[0, 9]}
/>
<YAxis />
<HorizontalGridLines />
<AreaSeries
data={data}
opacity={0.25}
fill="#556887"
stroke="#556887"
// tslint:disable-next-line jsx-no-lambda
onNearestXY={(value: any) => {
this.setState({ tooltipValue: value })
}}
curve={curveName}
/>
<LineMarkSeries data={data} stroke="#556887" fill="#556887" strokeWidth={3} size={3} curve={curveName} />
</FlexibleWidthXYPlot>
I tried both setting Range, Domain and tickValues on the xAxis but nothing seems to work...
How can I make the labels on the X Axis only be shown once each?
UPDATE 2:
I can limit the number of ticks by setting attribute totalTicks={data.length}
like this:
<XAxis
// tslint:disable-next-line jsx-no-lambda
tickFormat={(d: Date) => formatDate(d, { rawFormat: 'MMM' })}
tickLabelAngle={-45}
totalTicks={data.length}
...
/>
I wonder if there is a more elegant / "correct" way of controlling the intervals of the x axis ticks...??
