I have a website that is using the reactjs react-timeseries-charts component for displaying graphs.
For some reason, when using any other browser besides safari, it works as intended with no errors. When i try and open with Safari, the bar charts and line graphs come up blank and through an error in react-dom.development.js saying "unable to parse: d=12345NaN, 45678NaN". I don't quite understand how to troubleshoot errors logged in react-dom.development.js. Clearly the "NaNs" are the problem, but I dont know where they are coming from. When I examine the DOM elements, on Safari, the tag has x="NaN" that is not present in chrome, so the actual width of the bars is not being properly set. The X-axis is also not rendering.

Here is the relevant snippet from render():

}
Here is the relevant function for setting the timeseries:
let points = [];
let one = 0, two = 0, three = 0, four = 0;
for(let i in data){
if(some condition){
one++;
}else if (some other condition){
two++;
}else if (some other condition){
three++;
}else{
four++;
}
}
points.push({
"index": time,
"one": one,
"two": two,
"three": three,
"four": four
});
for (let i in data) {
const d = new Date(data[i].index);
const index = Index.getIndexString(interval, d);
points.push([index, data[i].one, data[i].two, data[i].three, data[i].four]);
if (points.length > 0) {
const series = new TimeSeries({
name: "BarChart",
columns: ["index", "one", "two", "three", "four"],
points: points
});
I made some changes to mask the nature of the code and what it is for, so there may be some typos with regards to that.
I do know that react-timeseries-charts is throwing errors for NaN height and y values when the data points contains a value of 0 for one of the four values (one, two, three, four), but it still renders in chrome.
Any help would be appreciated.

Reset to default 0Closing this. the documentation says react-timeseries-charts does not support safari.
Ended up migrating to ChartJS instead.
