Max number of points on scatter chart

I am new to plotly and are using the community edition of the web app. I’ve imported an Excel spreadsheet with 1686 rows and 2 columns. Column 0 (y-axis) is a large integer from 5,000,000,000 to 103,000,000,000 and Column 1 (x-axis) is a date-time field from 2010-07-01T07:55:18Z to 2014-07-08T07:55:18Z. I’m trying to create a simple scatter plot. The plot is created successfully, but with many fewer points than 1686, guessing there are a total of about 200 visible. If I look a certain entries in the spreadsheet, and look for the corresponding dot on the chart, in many cases there is nothing plotted for that x,y data pair.

In the JSON data for the plot, type:scatter and under marker | maxdisplayed:0 (guessing that means unlimited). If I change that number to 1 or 2, the chart displays only 1 or 2 points, so that number seems to have some effect. But setting it to 1000 or 2000 or 0 seems to allow a max of about 200 points displayed (zooming in doesn’t reveal more points). Also the “x” and “y” keys both have [1686] next to them, and seem to list all points.

Is there a way to display as many of the 1600 data pairs as possible?
