I have a demo project to show inventory trends, and the inventory of each product is frequently, there may be hundreds of inventory points in one day. Now I need to show the inventory report of one week,a month and more, the problem comes out---I have two series, one line disappeared when the points come to neer 3000(not accurate);the chart displays nothing when the amout of data is large(such as 7000 points and more) completely!
The demo is here CODE:demo here, the format of datapoints are like the demo, error occures when the point number is large,such as 4000 and more, you can try to mock up large data of this demo to find the problem.
Actully I see million points of data shows fine in others' demo, then I tried to min the size of the data points but failed, the problem still exists. How can I solve the problem?
You need to increase turboThreshold parameter, but for huge data we recommen to use Highstock which uses dataGrouping module, allowing to increase performance.

when I use the data below in a google sheets timeline chart it doesn't plot 29/04/2019 5% and 10% leaving a gap in a chart, how can I resolve this? the chart should be unaffected by empty fields.

I have tried adding another dataset and I get the error
each values column may be followed by one or two annotation columns. column number 4 is of type date
Here is a link to the spreadsheet
There are gaps in your data, so you're going to have gaps in your chart. That's just how Timeline Chart works. There are ways of having charts skip gaps, but you have the 29th as a date, so it is explicitly part of your timeline.
The least burdensome remedy is usually to chart a different dataset living elsewhere, filtered down live from your input values, but meeting your charting requirements. E.g. elsewhere in your file have it list only the rows where 5% Target is populated with something like =FILTER(B2:E,LEN(C2:C)) and then chart that.
If that's not what you really want, then you need to decide what you really want. A time-cropped chart to only include fully-populated date ranges? A chart with made-up values extrapolated from surrounding data? Those and some other options are not trivial, so you'll need to really determine your requirements and look into how they can be achieved.
I'm trying to create a formula that uses a dynamic range to link to the different tabs. It would then return the last 12 values before a blank cell, based on the value in the Header Column.
The tricky part is the data in each tab is of different sizes, so I thought it might have to incorporate either Offset(Blank()),0,-12) or something of the sort. I've tried a lot of different things, and this is the latest effort:
=Index(Indirect(A2&"!A9:AK9"),match("Conversions",Indirect(A2&"!A9:AK9"),)0,-12)
Edit: First post, sorry for the confusion. My goal is to make a large dashboard that has a dynamic chart using our monthly metrics. (I'm leaving the chart setup for another day)
The data varies in such, some have columns A:K, while some have a larger range of A:AK , etc. (With A:A being text). Since I've posted this, I have had some success by using Filter(), but the problem I'm not sure how to solve is finding the last 12 values before a blank cell.

Hopefully this helps explain the situation and I appreciate everyone for help.
I am using Rbuilder within a application constructed with Delphi. I have a report already built that displays a list of items but then at the bottom I have some subtotal fields as well as a total field. The subtotals and totals are defined as variables which then total up the cost of the individual items.
Unfortunately both the subtotals and totals only give me calculations for items on the first and last pages of data. Lets say there are 5 pages of data that prints out. Page one the totals are accurate.
Page two totals are accurate. Page 3 totals include ONLY the totals from page 1 and page 3. Page 4 total includes page 1 and page 4 and so on. I have been trying to play around with timing settings as well as moving my code calculating the total to different operations (ongettext, onprint, oncalc, etc)
Has anybody ever run into this?
Ok, so I kept working at this and eventually found the problem.
At the report level I changed the report from TwoPass to OnePass. That ended up giving me very close to what I wanted. I ended up having to write some more code to get exactly what I wanted but changing the number of passes worked.
I was trying to display a running total page by page. And as I changed pages it would update the value.
Onepass worked.
Im having trouble in ESPER.
I have a simulated stock file which conatins a lot of info.
I want to fnd all the start and stop dates when the weighted price of the BTC stock increases more than 100 times.
This is how the files looks. These are BTC stocks:
2010-07-18,0.04951,0.08585,0.05941,0.08584,75.01,0.07
2010-07-19,0.08584,0.09307,0.07723,0.0808,574,0.09
2010-07-20,0.0808,0.08181,0.07426,0.07474,262,0.08
IN ORDER EACH COMMA SEPARATION REPRESENTS:timestamp, open, high, low, close, volume, average
So basically im supposed to make a query that does what i said above^ which I cant seem to find out how. Im very new to CEP so im still reading it up.
Any help is much appreciated.
You could use "prev" to increase a count in a named window, or write an aggregation function against the API that aggregates the custom trend.
I'm trying to generate a stacked column chart. What I want is similar to this JSfiddle example. However, I have around 30 categories and 1000 series. The series are rather sparse. There are only about 200 values. But because highcharts needs each series to have values across the x-axis categories, I'm forced to submit 1000 series each having 30 values (mostly zeroes). The chart takes over a minute to render. How can I improve this performance?
There is another way you can pass the data to highcharts, where you specify x and y for each point. This means you can skip the 0 values. In the fiddle you quoted, I modified one line to be:
data: [{x:1,y:5}, {x:3,y:7}],
http://jsfiddle.net/rh9aK/
I expect that 1000 series and 30 categories may still be too much, but this is worth a try.
One other thing, have you made sure that you don't have any series which only contain zeros ? If so, you may as well remove them before rendering.
JS charts, in you case, will produce too many DOM elements. It will be too complex for browser. You need some server-side solution which generate graps inside image.
