问题
I am trying to update the data series on the update button by providing new series. As the result, new series will be a plotting along with the old series.
And After plotting the new series, the values on are X-axis is clear up. Here I Am attaching the code snippet please have look.
Initial State config:
this.state = {
chartOptions: {
credits: {
enabled: false,
},
chart: {
type: 'spline',
},
title: {
text: 'Chart',
},
plotOptions: {
series: {
shadow: false,
marker: {
enabled: false,
},
},
},
xAxis: {
gridLineWidth: 1,
type: 'datetime',
lineColor: '#999',
lineWidth: 1,
title: {
text: 'Time',
style: {
color: '#000',
},
},
},
yAxis: [
{
title: {
text: 'Value',
},
gridLineWidth: 1,
lineWidth: 1,
opposite: true,
plotLines: [
{
color: '#55c2ea',
width: 2,
value: props.data[0][1], // Need to set this probably as a var.
label: {
text: props.data[0][1],
textAlign: 'left',
verticalAlign: 'middle',
style: {
color: '#55c2ea',
fontSize: 16,
borderWidth: 1,
backgroundColor: '#55c2ea',
borderColor: '#55c2ea',
},
x: 330,
},
},
],
accessibility: {
enabled: true,
},
opposite: true,
},
],
time: {
useUTC: false
},
series: [
{
showInLegend: false,
color: '#FF0000',
data: props.data.slice(0, props.tradingInterval),
},
],
}
};
Update Function:
updateSeries = () => {
this.setState({ chartOptions: {
series: [
{
showInLegend: false,
color: '#FF0000',
data: this.props.data.slice(0, 15),}
]
} })
}
Graph Render code:
render() {
return (
<View style={styles.container}>
<HighchartsReactNative
styles={styles.chart}
options={this.state.chartOptions}
/>
<Button
title="Refresh"
onPress={this.updateSeries.bind(this)}/>
</View>
);
}
After updating graph looks like
