The out of the box TWX time series chart widget is notorious for poor performance when attempting to render that many data points. You can either look to a more efficient third party charting library like Plotly or run your data through the Interpolate service (infotable snippet) to reduce the number of data points.
The BEST option, provided you have direct access to your instance of Influx, is to resample your data. You can do this either on the fly or as part of some DB job that continuously maintains a subset of your data in another table. Whichever strategy you choose, there is no reason to render 13,000 data points. A resampling strategy will allow you to visualize your data within the specified time period. As your time period gets smaller and more precise you can then look to bring in data from the value stream. In your specific scenario, if one hour is approx 13k worth of data points, I wouldn't want to see the data in full granularity until I was looking at a time frame of only a few minutes.
