This section has details on all the different functions built into the top menu of NZGrapher. Click on each heading below to expand out that section.
Note: you can open the inbuilt datasets by using the drop-down in the top right of NZGrapher.
This allows you to open a file from your computer. File must be a csv.
Import from Clipboard
This allows you to import a table you have copied from Google Sheets, Word or Excel.
Note: it doesn't allow copying from Google Docs, as the tables come through with an unusual format.
Sometimes for large tables this can take some time to process... just be patient.
If you are having an issue importing from the clipboard it's important to make sure you've allowed access to the clipboard. For more on this see instructions here.
Paste Table (Legacy)
This allows you to paste a table you have copied from Google Sheets, Word or Excel.
Only use this if the import clipboard doesn't work, as is slower and doesn't allow for as much data to be imported.
Note: Pasting a table from Google Docs doesn't work properly.
This allows you to paste a link to a csv that is available on the internet.
You can publish Google Spreadsheets as a csv (File -> Publish to Web -> Sheet and CSV -> Publish), so this can be quite handy.
When you do this, the link to the page that NZGrapher goes to can be shared with students... eg: https://grapher.nz/?url=https%3A%2F%2Fdocs.google.com%2Fspreadsheets%2Fd%2Fe%2F2PACX-1vQeC_NBxkH-cp6pI7SV-C1PXP8dph-3t4A8eet13kDNSI7hO8ePJHdrhsxcONzzPSbnEdweOEIoNJ37%2Fpub%3Fgid%3D0%26single%3Dtrue%26output%3Dcsv
Select Data Table
This highlights the data table, if you want to copy it into a doc somewhere.
This downloads the data as a csv.
Save Current State for Reset
This saves the current state of the data for when you press the reset button. Useful for if you are adding extra columns / filtering and then wanting to sample and reset.
This resets the data to it's original state from before you made any changes to it (sampling or editing etc.)
Adds a blank row at the end
Delete Last Row
Removes the last row from the data table
Delete Specific Row
Brings up a popup asking which row number you want to delete. The number is the number from the id column on the left.
Adds a blank column at the end
Delete Last Column
Removes the last column from the data table
Delete Specific Column
Brings up a popup asking which column you want to delete.
Sample and More
Allows you to do either simple random samples, or stratified random samples.
This is also useful if you want to remove a particular section of the data... for example in the kiwi data set if you just wanted to look at GS and NiBr, you would set these to 163 and 275 respectively, and leave all the others blank and press sample.
Sorts the data table by a particular variable. This doesn't affect displays.
Allows you to prepend text (add to the start of) to a variable.
For example if you had a variable with values "N", "A", "M" and "E" and you wanted them to display in this order, you would put 1, 2, 3, 4 next to these respectively, and then it would graph in that order.
Create New Variable (From 2 Variables)
Allows you to add, subtract, multiply or divide two variables.
Create New Variable (Linear Function)
Allows you to create a new variable with an equation of y = m*x + c where x is one of the columns in the existing data set.
Create New Variable (From Condition)
Allows you to create "Low" or "High" variables. Conditions can be <, ≤, =, ≥, and >.
Create New Variable (Re-Group)
Allows you to regroup variables, for example if a variable has 5 groups, you can assign each group to a master group, so you have less overall groups.
Allows you to filter out numerical data, for example, only look at kiwis that weigh over 2kg.
Add Graphable Index Column
Adds a column to the left with the index number so this can be used when graphing.
Convert Time Column
Takes standard date / time fields and converts them to Seconds, Minutes, Hours or Days for graphing in scatter graphs or dot plots.
Encode Time Column
Encodes standard date / time fields into formats for use with the NZGrapher time series modules (eg: 2000M01)
Updates any manual changes you have made to the dataset to the graph and selection boxes at the bottom of the page.
Note: this doesn't permanently change the dataset saved on the server, it only saves changes while you are on the page.
