I have downloaded hourly stock data for AAPL for the past 30 days and am displaying a candlestick chart. The chart loads properly but the time shown for each bar is incorrect. I am in the Pacific time zone.
I tried changing the way the data table is created but none of the ideas below seem to help.
var dataTable = anychart.data.table(0);
var dataTable = anychart.data.table(0, '', 8);
I am using the same example as the one on the AnyChart website https://www.anychart.com/products/anystock/gallery/Stock_General_Features/Showing_Intraday_Data.php
Please see the following 2 images.
For the ORCL chart from the example on the AnyChart website, I clearly see the date and time (highlighted rectangle)
working example from AnyChart website
For my chart (for AAPL hourly data), the time is off and it shows "13 05 Nov 2021" etc.
Does not work for my data

Thanks to AnyChart for responding so quickly via email.
The following snippet solves the issue with the tooltips and now I can see the proper date and time on the tooltip.
chart.tooltip().titleFormat(function() {
return anychart.format.dateTime(this.x, 'yyyy-MM-dd HH:mm:ss');
});
To set the proper legend, the following code does it:
plot.legend().title().useHtml(true);
// configure the format of the legend title
plot.legend().titleFormat(
"<span style='font-weight:600'>" +
"{%hoveredDate}{dateTimeFormat: yyyy-MM-dd HH:mm:ss}</span>"
);

I am working with data where I need to create multiple scatter plots for different populations. I also recently upgraded from SPSS v26 to v28 and the code that I used for this worked in v26 but is no longer working correctly in v28. Instead of producing multiple scatter plots like it's supposed to, it is now producing 1 plot in v28, presumably the first subpopulation in the split. I tested the split file function with descriptives and it worked as intended.
I have scoured everything in the GUI menus to find any kind of setting that was ticked by default and came up with nothing. I also tried to use a filter based on the criterion variables in my split file function and ran a scatter plot but that gave me a graph of the whole population instead of the subpopulation I filtered. Any guidance on what could be going on with scatter plots and the split file function in SPSS v28 would be greatly appreciated.
Here is my code for reference:

I have a function on a js to create an anychart.stock
dataTable = anychart.data.table();
dataTable.addData(json);
price = dataTable.mapAs({'value': 1});
height = dataTable.mapAs({'value': 2});
weight = dataTable.mapAs({'value': 3});
var pricesChart= chart.plot(0);
pricesChart.grid().enabled(true);
pricesChart.grid(1).enabled(true).layout('vertical');
PricePlot = pricesChart.stepLine(price).stroke('#004400');
var heightChart= chart.plot(0);
heightChart.grid().enabled(true);
heightChart.grid(1).enabled(true).layout('vertical');
heightPlot = heightChart.stepLine(height).stroke('#334400');
var weightChart= chart.plot(0);
weightChart.grid().enabled(true);
weightChart.grid(1).enabled(true).layout('vertical');
weightPlot = weightChart.stepLine(weight).stroke('#334400');
When the plot is displayed all the scales can be seen OK. See this image:
The problem appears when I move the scroll to the right. It modifies the scale of my last chart causing this chart to be unreadable. See next image:
I just learned what happened to the visualization.
The problem is that given a period of time, for example, this year from 01-01-2019 to 31-12-2019 I am using three different lines to display information.
The first line contains info from 01-01-2019 to today
The second line contains info from today to 7 days ahead
The third period contains info from 7 days ahead to 31-12-2019.
The fact that the lines are not continuous is what is breaking the zoom.
I'm currently doing arima forecasting in R and i'm already on the last step of displaying the forecast result but I am having trouble in displaying the forecast on the graph.
Here is my code:
mydata.arima005 <- arima(d.y, order= c(0,0,5))
mydata.pred1 <- predict (mydata.arima005, n.head =100)
plot(d.y)
lines(mydata.pred1$pred, col="blue")
lines(mydata.pred1$pred+2*mydata.pred1$se, col="red")
lines(mydata.pred1$pred-2*mydata.pred1$se, col="red")
So as you can see, I want my graph to show the forecast values in color blue and the confidence interval on red. But this is what I am getting instead.
So as you can see it's not color coded at all. My code contains no error.
This is a sample of the output I am expecting(got it from youtube)I used the same codes used in this video I got thats why i was wondering why my graph doe not look like this.Hope you could help
The forecast package has some functions for displaying nice plots of the forecasts and prediction intervals.
You would need something like this:
library(forecast)
mydata.arima005 <- Arima(d.y, order= c(0,0,5))
mydata.pred1 <- forecast(mydata.arima005, h=100)
plot(mydata.pred1)
Or using ggplot2 graphics:
library(ggplot2)
autoplot(mydata.pred1)
I'm using Tapku calendar for my iOS app. I have something to do like this.
I'm getting a JSON array of data from the web service. It's something like this:

Each day has a particular colour to show on the calender. colour_id 1 -red,2-green and 3-yellow.
I can change the
- (NSArray*)calendarMonthView:(TKCalendarMonthView *)monthView marksFromDate:(NSDate *)startDate toDate:(NSDate *)lastDate
by giving dates with the colour id. My problem is how can I change the select image in Tapkucalenderby checking the colour_id coming along with a particular date.
This is what I need to do with my TapkuCalender
I have a TimeSeries Chart with a XYdataset which has the milliseconds of each dates.
Now I want to have a chart that only displays each date one time on the axis, no matter what the range of dates is. I already got it so far, that only the date is printed, not the time (via setNumberFormatOverride() method).
What I have now, is this:

This is a snippet of my code. also, the setLabelAngle() method don't work?!
JFreeChart chart = ChartFactory.createTimeSeriesChart(...);
XYPlot xyplot = (XYPlot)chart.getPlot();
DateAxis dateaxis = (DateAxis) xyplot.getDomainAxis();
dateaxis.setLabelAngle(Math.PI / 6.0);`
numberaxis.setNumberFormatOverride((DecimalFormat)DecimalFormat.getInstance(Locale.GERMAN));
You can set the TickUnit to any convenient DateTickUnitType. I use DAY in this example and MMM to verify the Locale:
axis.setTickUnit(new DateTickUnit(DateTickUnitType.DAY, 1,
new SimpleDateFormat("dd.MMM.yy", Locale.GERMAN)));
As you are a returning customer, I'll address the second question, too: setLabelAngle() works perfectly well, but it changes the axis label in the chart legend. Using setVerticalTickLabels() is an alternative for the tick labels themselves:
axis.setVerticalTickLabels(true);
